ANSWERED FTP Client (filezilla) behind airvpn cannot connect to any ftp servers.

[WarButter 2]

I am using filezilla as FTP Client and while i am connected to an airvpn server, I can't connect to any ftp servers.

Without airvpn it works fine.

Help please?

What do you see in the logs of your FTP client?

and that repeats. (i replaced the actual ip with <ip> in the log, i not actually connecting to "<ip>" that would be silly)

It's got to be something local.  Perhaps some Firewall permissions rule.  If not, is the server you are connecting to have an IP whitelist?

 

I use FileZilla all the time on Air and never once had a problem like that.

When i am on any other network without airvpn, it works flawless.
When I am on my own network without airvpn, it works flawless.

When I am on my own network with airvpn, it never works.

 

There are no whitelists, or anything. I'm not blacklisted either.

Can you try different servers? The only possibility here is that the IP you are connecting from (Air)

is firewalled from the FTP host you are connecting to.

 

You can also try connecting to public servers like ftp.debian.org to see that everything is working.

With all servers its the exact same problem.

Okay, tried disabling my firewall - no change -

I logged in on my nat that uses the airvpn and tried disabling the firewall and ftp works!

But i dont want to keep my nat firewall off, so now i need to know what to allow through.

You are probably using an odd networking setup that is not easy to troubleshoot.

You have to provide more details on this setup in order for us to understand more.

I have my laptop where i work on. The ftp client is here too.

My laptop is wired to my own server directly.

 

This server handles NAT, routing and runs the airvpn.

My server is connected to the internet.

[flat4 79]

what kind of firewall or NAT are you running

[WarButter 2]

I'm running windows server 2012 datacenter and the routing on there is done by RRAS (Routing And Remote Access) feature.

Oh, sorry have no experience with that.
