Always Same Exit IP

[UnevenSeven 0]

I find it odd that I always get the same exit IP address when connecting to Castor (haven't checked the other servers). I expected different addresses.

What am I missing here?

Thanks.

Hello!

It's correct, each server has one, shared exit-IP address.

Kind regards

So you know where to send that packet back via MAC address?

Thanks again

Hello!

AirVPN is based on OpenVPN in routing mode. The TUN device handles layer 3, IP packets, not Ethernet frames. MAC addresses are not part of IP packets at all. In order to route packets correctly OpenVPN performs "NATting". Of course there are additional rules in order to allow correct port forwarding to all clients that require it.

So if someone wanted to run an FTP server on the VPN, where would an FTP client connect to?

Hello!

You can find all the relevant information (especially for an FTP server behind a VPN server) here:
