To redirect all DNS and NTP requests on the interface, we actually have to create two port forwarding rules. Those rules have an option to automatically create an associated firewall rule with them, which we will take advantage of. We will start with the port forward rules, then create the rest of the firewall rules manually. Step 6-D: First AirVPN_LAN Firewall Rule "AirVPN LAN DNS REDIRECT" The first AirVPN_LAN firewall rule is actually a port forward + associated firewall rule that will redirect all DNS requests on this interface to the DNS server of our choice. In the interests of the majority of AirVPN users and for the purposes of this guide, this rule will force all users on this interface to use the DNS Resolver and hence the servers we entered on the general settings page(AirVPN's DNS), even if they have a manually configured or hard coded DNS. 1.) Go to Firewall / NAT / Port Forward http://192.168.1.1/firewall_nat.php -or- https://192.168.1.1/firewall_nat.php 2.) Click the [ ↓ Add ] button on the bottom right (When moused over it reads "Add rule to the end of the list") and create a rule we will title "AirVPN LAN DNS REDIRECT". Set as follows: -------------------------------------------------------------------------------------------------------------- Edit Redirect Entry -------------------------------------------------------------------------------------------------------------- Disabled = [_] (UNCHECKED) -------------------------------------------------------------------------------------------------------------- No RDR (NOT) = [_] (UNCHECKED) -------------------------------------------------------------------------------------------------------------- Interface = [ AirVPN_LAN ▼] -------------------------------------------------------------------------------------------------------------- Protocol = [ TCP/UDP ▼] -------------------------------------------------------------------------------------------------------------- Source = [☼ Display Advanced ] (CLICK TO SHOW ADVANCED OPTIONS) -------------------------------------------------------------------------------------------------------------- Source = [_] Invert match.

Click [ Save ] 4.) Click [ Apply Changes ] Step 6-E: Second AirVPN_LAN Firewall Rule "AirVPN LAN NTP REDIRECT" The Second AirVPN_LAN firewall rule is actually a port forward + associated firewall rule that will redirect all NTP requests on this interface to the NTP server of our choice. This rule will redirect all NTP requests to pfSense even if the client/device has a hard coded NTP server programmed. 1.) Go to Firewall / NAT / Port Forward http://192.168.1.1/firewall_nat.php -or- https://192.168.1.1/firewall_nat.php 2.) Click the [ ↓ Add ] button on the bottom right (When moused over it reads "Add rule to the end of the list") and create a rule we will title "AirVPN LAN NTP REDIRECT".

Click [ Save ] 4.) Click [ Apply Changes ] Step 6-F: Third AirVPN_LAN Firewall Rule "ALLOW_LOCAL_ICMP" *NOTE: You should have two default firewall rules as well as the two associated NAT rules from our DNS and NTP redirection rules already set. The two default rules are the “anti-lockout rule” and a “default allow LAN to any” rule. Do not touch the anti-lockout rule. DELETE THE "DEFAULT ALLOW LAN TO ANY" RULE AT THIS TIME. 1.) Go to Firewall / Rules http://192.168.1.1/firewall_rules.php -or- https://192.168.1.1/firewall_rules.phpand Select your "AirVPN_LAN" interface. 2.)

Click [ Save ] 4.) Click [ Apply Changes ] Step 5, Part 2: Basic Port Aliases To admin our firewalls to be as secure as possible, you have to take the mindset that it is going to take a bit of effort. It starts with learning how the protocols are intended to work. Put short, only ports (services) that we intend to be running should be allowed. Thankfully, pfSense makes this somewhat easy in the fact that by default EVERYTHING is blocked by pfSense unless we create a rule to allow it. I have gone out of my way to offer basic ports to enter for an "entry level" port alias that will allow you to take first steps at becoming your own personal network security admin. These ports will cover the ports (services) that clients on your networks should be allowed to use. To start off and to make this as beginner friendly as possible, the basic rules will only cover the "Well Known Ports" range of 0-1023. That being said, this step is going to require some user interaction as not everyone will have the same needs. Some people won't need an FTP port allowed on the local network, and some people might need IMAPS open on a local network if they have their own email server. Add or remove ports to these rules as needed. I fully encourage discussion in the forums so common services can be brought to everyones attention and added to the list. With or without that discussion, here is some basic info on ports and their assignments. I encourage anyone not already familiar to read up on the subjects of: Well Known Ports: 0 through 1023 Registered Ports: 1024 through 49151 Dynamic/Private or Ephemeral Ports : 49152 through 65535 Some quick links for further reading on the subject: List of TCP and UDP port numbers - Wikipedia Service Name and Transport Protocol Port Number Registry - iana.org THIS WILL BE THE MOST CHALLANGING PART OF THIS GUIDE, YET THIS IS ONLY A BASIC SECURITY PRECAUTION! I will offer an advanced port alias section soon that will also cover controlling the "Registered Ports" port range of 1024 - 49151. Step 5, Part 2 - A: "LAN_SERVICE_PORTS" Alias LAN Service ports are ports that clients on our network will be allowed to connect to on the local network. These connections DO NOT leave the firewall to the outside internet. You will need to include ports for any service you have on your LAN (Local Area Network) that falls within the "Well Known Ports" range of 0-1023. 1.)

Go to: Interfaces / Interface assignments http://192.168.1.1/interfaces_assign.php -or- https://192.168.1.1/interfaces_assign.php 2.) Find the line "Available network ports:" and set as follows: Available network ports: = [ ovpnc1(AirVPN) ▼] 3.)Click the [ + Add ] button on the lower right for "Add selected interface" 4.) Click [ Save ] 5.) While still on the assign interfaces page, find the link for your newly created "ovpnc1" interface by "mousing over" it's name and select it. This will bring you to the configuration page for this interface.

Find the button under the actions section on the same line as AirVPN_WAN_VPN4 that looks like overlapping sheets of paper (shown here as ☐) and select it. ***** NOTE: THE APPEARANCE OF THE FOLLOWING IS BASED ON A FRESH INSTALL AND ASSUMES YOU HAVE FOLLOWED THE PREVIOUS STEPS IN THIS GUIDE!

This was to act as a fail-safe in the event something went wrong, all traffic would attempt to route through the VPN and have no chance of being re-routed to the clear_net. While this "works", THIS IS NOT CORRECT FROM A ROUTING STAND POINT. Trying to use it this way causes what is known as a routing loop and can quickly exhaust network buffers. This can be seen in the OpenVPN Logs when using the "verb 4" setting. It shows up as: write UDPv4: No buffer space available (code=55)The idea of having the VPN as the default gateway is nice on paper, but should not be used. If all other settings are correct, this is not an issue and should not be worried about. Focus instead on having all settings correct! 4.) Click [save] 5.)

Go to: Firewall / NAT / Outbound http://192.168.1.1/firewall_nat_out.php -or- https://192.168.1.1/firewall_nat_out.php NOTE: By default the "Mode:" selected is "Automatic outbound NAT rule generation (IPsec passthrough included)". Below this you will see a sort list of rules that are not accessible. We need to change the "Mode:" to "Manual Outbound NAT rule generation (AON - Advanced Outbound NAT)" so that we may edit these and create new rules as needed throughout setup. 2.) Set as follows: Mode: = Manual Outbound NAT rule generation (AON - Advanced Outbound NAT) 3.) Click [save] 4.) Click [Apply Changes] A now accessible list of rules should appear. We will delete the "Auto created rule - LAN to WAN" Since our "LAN" interface will become our "AirVPN_LAN" interface. Further, outbound NAT setup will be addressed per interface in that step's instructions.

If you do not use IPSEC, those two rules can safely be deleted by clicking the trash/rubbish button to the right of that rule. Most people will not need these rules since we are using OpenVPN, so going forward in this guide further instructions will have those rules ommited as if they were deleted. If you do need them you can keep them, it will not hurt the setup. 5.) Click the buton shaped like a trash/rubbish can to the right of the "Auto created rule for ISAKMP - localhost to WAN" rule to delete it. 6.) Click the buton shaped like a trash/rubbish can to the right of the "Auto created rule for ISAKMP - LAN to WAN" rule to delete it. 7.) Click the buton shaped like a trash/rubbish can to the right of the "Auto created rule - LAN to WAN" rule to delete it. Now we are left with: Outbound NAT after deleting unneccesarry default rules.

Setting Up pfSense 2.3 for AirVPN Step 2: Understanding and Entering our AirVPN CA, Certificate and Key Step 2-A: Understanding Certificates and OpenVPN Config Files I noticed on the forums that many people trying to set up pfSense struggle with entering their certificates properly. I will try to be as detailed as possible here. First, if you have not done so already, we have to download the OpenVPN Config File (.ovpn) for our preferred AirVPN entry server (We will need the direct IP address of the server as DNS will not function until the VPN is up.). You can do this by logging into airvpn.org and then proceeding to https://airvpn.org/generator/ . Choose the entry server of your choice (the air entry server can be changed later whenever you need, we will focus on one for this tutorial) by selecting the corresponding check box, then scroll down and select the Direct, protocol UDP, port 443. Scroll down again and select both check boxes agreeing to the AirVPN terms of service, then click the Generate button. Once you have the config file you can open it with your favorite text editor. What you should see will look very similar as the sample ovpn config I pasted below (this one was downloaded for a windows client). The config is broken into FIVE main parts that we will need to identify for our uses. The five parts are as follows: Settings and Advanced SettingsCA (Certificate Authority, everything between <ca> and </ca>)Cert (Certificate Data, everything between <cert> and </cert>)Key (RSA Private Key, everything between <key> and </key>)tls-auth (2048 bit OpenVPN static key, everything between <tls-auth> and </tls-auth>) Sample OpenVPN Config File We will need to copy these settings, from YOUR own config file that you downloaded from the AirVPN config generator, into pfSense to set up our certificates and OpenVPN.

Do yourself a favor and wait a week or two. This guide will be completely outdated in the coming days as the release of pfSense 2.3 is very near. I am working on a new guide that is far more in depth than the current one, but it will take some time to edit my BBCODE and have some users test it before releasing it. I wouldn't waste your time right now.

I need feedback from users who have done a fresh install of pfSense 2.3 What i need to know is if the DHCPv6 server is enabled on the LAN interface by default for you. Please let me know, as I am trying to accurately update the guide to 2.3.

Those openvpn options have no affect on your interface options. if your servers are accessible then I would have a look at your outbound NAT and your gateways.

For sure, wouldn't hurt to have an experienced user look it over. Anyone else want to have a look at it? I would like to send a group invite, hope to get a few more.

All the same, the update I'm making should work for 2.3 as well. If not I can add the steps to the thread and add links in the index as the main guide goes to 2.3. That being saidI came on here to see if there are any other takers that want to help me audit/preview the new guide before posting. Any takers? I can invite to a private thread.

That's quite OK. I want this guide to be accesible so it's OK if you have a lot of questions. It will help me nail the update down.

Thanks guys. I'm still so new that I have to wait for moderator clearance, and so my post came in after you replied. I assumed there was some kind of string shenanigans going on. Glad it was something simple. And pfSense_fan, as soon as I'm clear of this low post count censorship, I'll try to get you more feedback. Your guide single-handedly kept me using AirVPN. Without it I would have been lost in the sea of pfsense generic documentation. Thank you, that's a very nice compliment. I remember feeling that way, it's what lead me to make this. Everywhere I looked, every "guide" seemed like it was written for people who already knew how to do it. It's almost as if it is an inside joke with open source software, "Here's how to do XYZ, assuming you already know how to do ABCDEFG...". It was maddening. That being said, I am working on a major update to the guide. Any interest in previewing it to help me spot any errors and possibly beta test it? I can invite one more person into the private thread. Let me know.

It should be fixed now. That's what feedback is for. I didn't know there was a line limit. Thanks for the heads up. The comments are fine left in otherwise, they are there and have been in my setup, except the explanation for using remote.

I like this to.Tokeep google out of the loop ,is always a good idea . If I understand this right, you want to use the Resolver in combination with Airvpn dns? Have a good day. Gr,casper. Correct, the update migrates to the DNS Resolver, and the guide will focus on AirVPN DNS. The user can use the DNS of their choice. No joke, I thought about this as I lay in bed last night. Problem is I have never attempted it. I would like to add this but have no timetable for such an addition. Once I'm done with the core parts of the guide I will explore this, but that's not saying much for when that might be.

REQUESTING FEEDBACK AGAIN! As I go through and reorganize the guide, there is a need to change the "basic" firewall rules that this has utilized. I intend to be a bit more in depth going forward. That being said, I have an tweak that I want to use, but want to make sure others agree it is a good idea. This tweak has to do with DNS and NTP. More and more these days, IoT devices, apps and any number of devices are coming hard coded with DNS and NTP servers. Apple devices such as iphones and ipads query hard coded NTP. Android apps are coded for google DNS. New Netflix apps are hard coded for google DNS as well. The list goes on. For a number of reasons, this can lead to configuration and/or security issues. Many of these devices and apps do not have an option to change these settings. I can make a firewall rule that will redirect all requests for DNS and all requests for NTP to the server of our choosing, best served by pfSense itself since it acts as a DNS caching server and NTP server. In the case of trying to get such devices and apps to use AirVPN's DNS for anti georestriction reasons or other, this is the best fix. I use this method and have for a few years. The question is, do you see the value in it as well? Should i include this as part of the guide? I feel like yes since this is a growing trend in devices and apps, but don't want to force my views on others. Let me know, discuss.

If you are using the DNS Forwarder, change the DNS entries on the General settings page to your DNS of choice and select the gateway you want to make the request on in the drop down box to the right of it. If you are using the Resolver, enter you DNS of choice on the General settings page, select the gateway as "None" in the drop downs. The go to the Resolver settings and select only the VPN gateway from the "Outgoing Network Interfaces". If you are allowing clients to query other dns servers, you need to make a policy based firewall rule that tells all traffic destined for your DNS server of choice on port 53 to go out the vpn gateway. do this by selecting the gateway from the advanced otions. this firewall rule needs to be at the top of the list on the interface you are on.

Step 3, under the advanced options adding the round robin when you're connection goes down and it goes to a different server, do yo need just IP's? certs and all that info is not needed? i would like to see the more secure settings also not to only improve my setup but knowledge. Correct, just need to add the IP addresses and commented out descriptions (if desired). Yours certs do not change per server, you have one certificate tied to your account that lets you connect to any air server, the only thing that changes on the certs you download is the individual server details such as IP and port. 1.I am interested to !And have test hardware. 2.in step3 ##### CLIENT OPTIONS #####; server-poll-timeout 10 ### When polling possible remote servers to connect to in a round-robin fashion, spend no more than n seconds waiting for a response before trying the next server. ###; explicit-exit-notify 5; I am almost sure that you forgot the " ;" after-timeout 10 . Can you confirm this? Gr,Casper 1. Perfect, glad to have another tester, that being said, our testing last night exposed some details I have to change to other steps. Once I have those done, I will PM you the new bits. Forewarned, it may be a number of days. There is a lot to consider 2. Nope, did not forget... it is at the end of the line. The ";" signifies a line break, it has no other function. If you wish to see what it does when you submit these entries you can go to: https://192.168.1.1/edit.php On the line toward the top that says "Save / Load from path:" Enter: /var/etc/openvpn/client1.conf Then click load. You should see all the entries pfSense adds through the GUI settings and all of our settings, each on it's own line. Glad to hear!

No issues for me here. I only have a few hardwired connections. The vast majority are through a wireless AP, so I just don't feel I need all the VLAN's in that setup. So I would be very interested in your updated perspective. I have learned a lot about pfSense since following your initial guide. Ultimately, I'd like to have it running your 3 NIC setup (when I get my C2758 board) connected to Air constantly, internal DNS resolution (via hostname) and Suricata for that extra security. Glad to hear that. It's nice to know people are still learning, just I I had a few years ago. I just finished the bbcode for the DNS resolver. Care to beta test it with my guidance? I can PM you instructions. Edit: I PM'd you in case you do.

That guide you looked at is based off of the same alias and port sets that I am referring to. Only required outbound ports should be allowed on outbound rules, only required local ports should be allowed on local rules. The changes I am proposing would be near identical except this guide focuses on physical ports instead of VLANS.

To any users who use, rely on or are thinking about using this guide and pfSense to connect to AirVPN... I AM LOOKING FOR SOME FEEDBACK BEFORE I PUT THE FINAL TOUCHES ON UPDATING THIS GUIDE! In updating this guide to use the DNS Resolver instead of the DNS Forwarder, a number of changes were required. The order of the steps even had to be changed. I have worked out the new order of things, and am in the process of touching up details and the BBCODE I use. As I do that I have an itch to slightly evolve the guide to be a bit more in depth and probably a bit more complicated. With that said, it would also be more secure. I am thinking about adding in a step to create a group of aliases that would in turn assist in creating more in depth firewall rules.These settings have extensive testing by myself and others for over a year now, if not two. So to you, who uses this, does that sound like something you would want to venture into, taking this to the next step? Please let me know! Discuss!

That would be hard to say for sure, but pfSense does not send out crash reports without you submitting it. When you get a crash report it asks you what you would like to do next.

Step 3: Setting up the OpenVPN Client - Has been thoroughly updated to align with the GUI settings of 2.2.6, plus some other tweaks that I believe should be used. Step 5: Setting the AirVPN Gateway - Has had minor pfSense 2.2.6 GUI appearance tweaks and minor settings tweaks (now recommend to disable gateway monitoring on all version prior to pfsense 2.3) As always, feedback is welcome and encouraged.

For anyone who is interested, I am working on some final updates to this guide to bring it up to 2.2.6 (or 2.2.7 if they for some reason have another release before 2.3). I want to leave this guide up to date for the final 2.2.x release for those who choose not to al all or postpone updating to 2.3. The main update will be including how to use the DNS Resolver. The Forwarder (DNSMasq) works fine, but the Resolver (Unbound) has some nice features up it's sleeve. I am going to offer it up differently than I originally did with the forwarder. Instead of useing clear-net DNS for the system and handing out the VPN DNS via DHCP, I intend to reverse that. The system will use the VPN DNS and any Clear-Net interfaces will have to hand out external public DNS if the user desires it. This could cause some confusion, as if the vpn goes down so to will the DNS Resolver. Others will find that fact desirable. I don't find it desireable myself, but to make the most use of the Resolver (Unbound) it needs to be. Unbound supports DNSSEC. This also allows users to make the most of the pfSense package "pfBlockerNG" and it's DNS block list functionality. In the interim, any and all constructive criticism is welcomed. As some know, I made this guide in my head to help users get started, my own setup is more complex, so I can't just refer to my own install. If anything else causes confusion or needs a tweak, please let me know.
