Setting Up pfSense 2.3 for AirVPN

 

Step 1: Disable IPv6 System Wide

 
 
    
 
  
 

Step 1-A: Disable DHCPv6 on WAN Interface

 
 
  
 
 
By default, the DHCPv6 client is enabled on the WAN interface. The following steps detail how to turn it off.
 
1.) Go to: Interfaces / WAN
http://192.168.1.1/interfaces.php?if=wan
-or-
https://192.168.1.1/interfaces.php?if=wan
 
 
Set as Follows:
--------------------------------------------------------------------------------------------
 General configuration
--------------------------------------------------------------------------------------------
                Enable = [√] (CHECKED)
--------------------------------------------------------------------------------------------
           Description = [ WAN_dhcp ]
--------------------------------------------------------------------------------------------
    IPv4 Configuration = [ DHCP ▼]
                  Type
--------------------------------------------------------------------------------------------
    IPv6 Configuration = [ None ▼] <----- (CHANGE THIS TO "NONE"!!!)
                  Type
--------------------------------------------------------------------------------------------
           MAC Address = [______] (Blank/Empty)
--------------------------------------------------------------------------------------------
                   MTU = [______] (Blank/Empty)
--------------------------------------------------------------------------------------------
                   MSS = [______] (Blank/Empty)
--------------------------------------------------------------------------------------------
 Private Networks
--------------------------------------------------------------------------------------------
Block private networks = [√] (CHECKED)
          and loopback 
             addresses
--------------------------------------------------------------------------------------------
  Block bogon networks = [√] (CHECKED)
--------------------------------------------------------------------------------------------
 
2.) Click [Save]
 
3.) Click [Apply Changes]
 
    
 
  
 

Step 1-B: Disable DHCPv6 Server on LAN Interface

 
 
  
 
 
By default, the DHCPv6 server is enabled on the LAN interface. Check here to see if it is enabled. My appologies for this being a somewhat incomplete step, but it is disabled on my system and I am unable to see what the user interface looks like here. I hope to update this eventually.
 
1.) Go to: Services / DHCPv6 Server & RA
http://192.168.1.1/services_dhcpv6.php
-or-
https://192.168.1.1/services_dhcpv6.php
 
2.) If you can see your LAN interface here, adjust the setting to disable it. Also save and apply settings if necessary.
 
    
 
  
 

Step 1-C: Disable IPv6 Configuration Type Setting on LAN Interface

 
 
  
 
 
By default, an IPv6 configuration type is enabled on the LAN interface. The following steps detail how to turn it off.
 
1.) Go to: Interfaces / LAN
http://192.168.1.1/interfaces.php?if=lan
-or-
https://192.168.1.1/interfaces.php?if=lan
 
 
Set as Follows:
--------------------------------------------------------------------------------------------
 General configuration
--------------------------------------------------------------------------------------------
                Enable = [√] (CHECKED)
--------------------------------------------------------------------------------------------
           Description = [ LAN   ]
--------------------------------------------------------------------------------------------
    IPv4 Configuration = [ Static IPv4 ▼]
                  Type
--------------------------------------------------------------------------------------------
    IPv6 Configuration = [ None        ▼] <----- (CHANGE THIS TO "NONE"!!!) 
                  Type
--------------------------------------------------------------------------------------------
           MAC Address = [______________] (Blank/Empty)
--------------------------------------------------------------------------------------------
                   MTU = [______________] (Blank/Empty)
--------------------------------------------------------------------------------------------
                   MSS = [______________] (Blank/Empty)
--------------------------------------------------------------------------------------------
 Private Networks
--------------------------------------------------------------------------------------------
Block private networks = [_] (UNCHECKED)
          and loopback 
             addresses
--------------------------------------------------------------------------------------------
  Block bogon networks = [_] (UNCHECKED)
--------------------------------------------------------------------------------------------
 
2.) Click [Save]
 
3.) Click [Apply Changes]
 
    
  
 

Step 1-D: "Disable" IPv6

 
 
  
 
 
1.) Go to: System / Advanced / Networking
http://192.168.1.1/system_advanced_network.php
-or-
https://192.168.1.1/system_advanced_network.php
 
 
IPv6 Options
Allow IPv6 = [_] (UNCHECKED)
From pfSense:
All IPv6 traffic will be blocked by the firewall unless this box is checked.
NOTE: This does not disable any IPv6 features on the firewall, it only blocks traffic.
 
NOTE: No other settings on this page were altered from default.
 
2.) Click [Save]

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 Settings
  • CA (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 NOT USE THESE, THEY ARE FICTIONAL.

          Disabled = [_] (UNCHECKED)

NOTE: The monitoring service has caused more issues then it has
corrected as of late, so we will disable it.

------------------------------------------------------------------------------------
 
 
***** NOTE: In the past, the default gateway setting was advised to be checked. 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!

Step 4-C: Setting the Localhost Outbound NAT to Include the AirVPN_WAN

 
 
  
 
 
Now that we have added a new Gateway, we need to add outbound NAT rules to allow the firewall (pfSense itself) to use that gateway.
 
1.) 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.

The two rules that use "STATIC PORT: ✔" and with "ISAKMP" in their respective descriptions are the default rules for IPSEC passthrough. 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:

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: Firewall: Aliases: IP
http://192.168.1.1/firewall_aliases.php?tab=port
-or-
https://192.168.1.1/firewall_aliases.php?tab=port
 
2.) Click the [ + Add ] button to "Add a new Alias"
 
Set as Follows:

Step 6: Setting Basic Firewall Rules for the AirVPN_LAN Interface

The following steps control/redirect ALL DNS and NTP requests,
define allowed local networks and services/ports,
enforce the policy based routing (tell outbound traffic to go through the VPN)
and define allowed outgoing networks and services/ports.

 
 
    
 
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

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".

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".

Set as follows:
--------------------------------------------------------------------------------------------------------------
 Edit Redirect Entry
--------------------------------------------------------------------------------------------------------------
               Disabled = [_] (UNCHECKED)
--------------------------------------------------------------------------------------------------------------
           No RDR (NOT) = [_] (UNCHECKED)

Setting Up pfSense 2.3 for AirVPN

 

Step 7: General Settings, Advanced settings and Other Tweaks

 
 
    
 
 
  
 

Step 7-A: System / General Setup

 
 
  
 

NOTE: Here we will set a system wide DNS which the Resolver (Unbound) will use in forwarding mode using AirVPN’s internal DNS servers.

 
With this method all requests to the built in DNS in pfSense, including requests from pfSense itself, will go through AirVPN’s DNS. To use this method you MUST use direct entry IP addresses in the openvpn configuration as your pfSense appliance will not be capable of resolving a domain name prior to the VPN tunnel being up.This method also means that if the VPN is down, there will will be no DNS resolution for any client on the system, even ones not using the VPN, unless an alternate DNS is handed to it via DHCP or manually programmed. Alternate DNS servers, inside or outside of the VPN, can be configured in the DHCP section on a per interface basis or more finely on a static DHCP reservation and with corresponding firewall rules and outbound NAT if it is needed.
 
1.) Go to: System / General Setup
http://192.168.1.1/system.php
-or-
https://192.168.1.1/system.php
and set as follows:
 
NOTE 1: You may set the hostname and domain to whatever you like, however if you do not know what this does, leave it alone
NOTE 2: For more information on NTP pools or more accurate servers see: How do I use pool.ntp.org?)
NOTE 3: Settings in the "webConfigurator" section are not covered here because they are purely optional

5.) Click [Yes] to Reboot
 
 
  
 
 

Step 8-C: Verifying Our DNS Settings (Optional Step)

 
Here we will test to see if domain names are resolving from the DNS servers we entered on the General Setup page. We will do this using the built in feature of the firewall.
 
1.) Go to: Diagnostics > DNS Lookup
http://192.168.1.1/diag_dns.php
-or-
https://192.168.1.1/diag_dns.php
 
Set as Follows:
Hostname or IP = [ airvpn.org ]
 
2.) Click [ Lookup ]
 
3.) Verify the results:
Hostname or IP = [ airvpn.org ] = 5.196.64.52
If 5.196.64.52 was returned it is resolving correctly. Feel free to resolve as many sites as you wish! This is a useful tool to keep in mind as well.
 
 
    
 

That's it! You should now have a functional connection to AirVPN! Just plug your ethernet cord, switch or wireless access point into the AirVPN_LAN port and you are off and running! I hope this guide helps you! Don't forget to back up your settings you just spent all this time setting up!
