Open port problems

[meerkat7 0]

Hi i have installed airvpn on my router (asus wrt) and all went swimmingly, however when it went to open ports i had issues so i had to stop the vpn.

One of the ports i tried to open gave the message that they were already being used by another user? i,m trying to open 3 ports in total, i managed to open one port but it directed the port to my laptop i think which i dont want, i want to open ports on another device that is connected to my router but there seems to be no option to select a different internal ip for the device i want the ports open on.

I tried deleting the ports that were originally open on my router but it made no difference.

Also the ddns i had to input that with no dots? am i doing that right?

Any help is well appreciated

Hi, just an update, i have seen how to add my ports in iptables on the router so i will manage that but i am still not sure of some things if someone can help..

I have a netgear nighthawk with asus wrt merlin ( NG Branch: 384.11_2 ) and i,m not sure which tun i input, also wondering if i still open ports in members area as well as iptables on my router.

Port XXXXX already reserved by another user.  This message appears in red also when i try to forward one of my ports in the members area.. i replaced my port with X

Any help greatly appreciated.

Every port can only be forwarded to one specific user, of course. Simply click Add and configure your client to use the port the system chooses automatically. If you need a specific port, you can always forward a random remote port to that specific local port, though other users (or you) must use the remote port in order to connect to whatever you forwarded that port for.

If you enter ddns, you can reach it via ddns.airdns.org:yourremoteport.

No idea how to do that...it will take a week for this post to be moderated... and by which time i will have grown a beard....

Don't be so negative.. you're online.

First mask is the remote port you want to forward. Let's say you entered 9000. People must connect to you by using that port, e.g. 1.2.3.4:9000. If you enter nothing, a random free port will be forwarded.
In the protocol menu you select TCP, UDP or both. Leave it.
Local port is to which local port a connection to 1.2.3.4:9000 will be forwarded. If you enter 80, you need to configure your local software to use port 80, but people must still use port 9000 to connect to that software. If you enter nothing, the remote port (9000 here) will be forwarded to the same local port 9000.
If you enter myname into DDNS, people can additionally use the domain myname.airdns.org:9000 to connect instead of typing out 1.2.3.4:9000. If you enter nothing, people must use the IP.

Hope that clears up things a bit.

Hi giganerd, sorry for the negativity, it was directed at the forum owners who decided to take an age to moderate my posts...not sure how long this post will take to moderate either, in post 2 i had an update which took ages for them to moderate so things got confusing... 

If i may can i start on fresh heels here... with your patience ofcourse giganerd.

I have found out some of my ports i cannot open properly as they are already taken... thats fine i can change that but one of my ports is ok so i can go ahead, 2 ports i will change and adapt to router but i dont know which tun to use...tun1?... its a netgear nighthawk r7000

Also some of my clients already use my own ddns... do i need to change that on all clients or can they still connect to my ddns once i have selected the ports, i have already selected ports available within airvpn

In ddns i had to use it with no dots... ie myddns.dyndns,net changed to myddnsdyndnsnet      is that ok

Does my clients have to now use airdns.org if i open ports properly.

Many thanks

Moderators are people, too, who work, sleep and live their lives. In a more or less anonymous setting like this it's easier to forget that, but they are not supposed to sit around all day moderating these forums. Anyway, you will be removed from the mod queue after five approved posts, and as I can see you only need one more.

Do you have multiple (OpenVPN) connections on the same machine running? If not, there should be one tun interface only and it's usually tun0.

Honestly, not sure what you're asking.. maybe it's the ambiguity between "my own ddns" and "airvpn"? What do you mean by the first and what by the second?

Erm, it should be with dots, it's how DNS works. Where do you enter such a thing?

They can still use both the DNS name (myname.airdns.org) or the IP, but the IP is considerably harder to access because it changes when you switch servers.

Thanks giganerd, apoligies to all including @admin, i got a bit lost, maybe too many drinks and lost patience which is not my strong field and then i got frustrated.

Anyway i am only using one vpn connection which is airvpn so i will try tun0 (thanks giganerd)

The ddns i am trying to input is one from noip which will update on my router or i can manually update my server ip on the said website if i have to, however if i try and input my noip ddns in the client area on airvpn while opening ports i recieve this message ( DNS name 'xxxxxxxx.ddns.net' invalid. Only the following characters are allowed: abcdefghijklmnopqrstuvwxyz0123456789- )

I have replaced my user with x for security purposes... if i input my ddns while opening ports in airvpn website from noip with no dots it accepts it...just a bit confused there and hope its clear.

Apoligies again for the negativity and thanks again for your help giganerd.

Oooh, I understand now what you are trying to achieve, but that won't work. You want AirDNS to tell No-IP your IP address but it's not the purpose of this feature.
What you really do with it is to give a name when forwarding a port and then you can reach your OpenVPN client by connecting to that name.airdns.org along with the port you forwarded (if it's port 9000, you connect to your client via name.airdns.org:9000). This is not a mask for DDNS domain names from other providers.

I have opened the ports with server names as advised by yourself giganerd but i am still having issues, can you tell me how i tell noip my address via airvpn.

I tried recently there to activate my vpn in my router and my browsers all acknowledge the new vpn ip but my own ddns will not update.

You still don't do that directly. But there might be a way to make it work.

If you can enter CNAME or Alias entries in your No-IP.com account, you can enter name.airdns.org as destination/target/value/whatever it's called, name being what you entered in the DDNS field on port creation.

Thanks giganerd, i dont seen to have that function on my noip account unless i am missing something but its a great idea, i can manually update my ip to the ip issued with airvpn but i suppose thats going to be an ongoing procedure and i dont even know if my clients will connect to my wan ip or airvpn if i do that.

My only other option i think is to change my clients over to servername.airdns.org , your input on that move would be appreciated too giganerd, bit of a faff but if thats what i need to do then so be it, i think i have exhausted enough of your time buddy on this and admin aswell.

Although if i can push the boat out once more, i have a netgear nighthawk with illegal software i am told so trying to get support is taxing it seems, i can move to tomato advanced but the software seems to be a tad outdated, dont know if thats due to it being rock solid or support has just stopped so i,m a little apprehensive to change over.

So i want to stay with asus xwrt on my netgear but i have read the commands will be different than the iptables commands already posted here and elsewhere , if you have time advice on the correct commands would be appreciated too giganerd.

Many thanks for all your time and help giganerd, really is appreciated.

Not when you only ever connect to one single server. They will connect to whatever IP you manually enter, and since AirVPN exit IPs don't change it could work. But you still need to connect to only one server.

Yes. If you want to be connected the whole time, it's the recommended solution.

I don't, sorry. But others surely can help with this.
