There is a bit more to it than just changing your port.
You'll need to run Neocron through a program called SocksCap32 (or FreeCap which also works in x64) so that it can utilize a proxy.
From what I've been able to figure, the only way to get Neocron to work through a network like this is with a Socks proxy.
An ssh tunnel doesn't work because ssh doesn't let udp through. I've been able to get to the character selection screen with an ssh tunnel, but after selection, I just get a sync screen.

The only problem with using a Socks proxy is that they seem to use port numbers which are quite certainly blocked. I thought that I could go around that by connecting to the socks proxy through an ssh tunnel, but it seems that the network I tunneled to also blocks Socks proxies.

tl;dr: find a socks proxy and use it. if that doesn't work, find an ssh tunnel and use the socks proxy through that.
Socks proxy through HTTP may work, although expect it to be laggy because UDP is blocked.

I used to use this in my first year to tunnel stuff that required UDP connections, as i could tunnel TCP only through SSH.
