I started writing a tutorial for you, but then I couldn't find a SOCKS proxy, so the part that I did write became fairly useless, since I'm not exactly sure how to implement it without actually trying.
I'll paste it in here for educational purposes, but it won't solve the problem of not being able to play Neocron.
This part is pretty simple, finding the servers is the difficult part.
You'll need
PuTTY for the SSH tunnel, and
SocksCap32 or
FreeCap for the Socks Proxy.
First, enter the hostname, and if it uses a non-standard port (which may mess things up) enter that. You may want to enter a session name to save it so that you won't have to reenter everything every time you want to use it.

After that, you need to go to Connection -> SSH -> Tunnels
You'll want to add a port and set it to dynamic.
This will be your tunnel port, so anything trying to exit your computer through that port will actually exit through the SSH tunnel on port 22.

Go back to the session screen if you want to save it. Once that's done, you can click Open to start the SSH tunnel. It will ask you about a key the first time you connect, you will want to accept it.
You'll then need to login to the server with your username and password.

You can now do simple things like look at porn on the internet, download porn from the internet, and download porn via torrents without them knowing it.(ask me about configuring your browser/torrent program if you want)
Again, an issue could be that they suspect you by your bandwidth usage.
It won't work to just run Neocron through the SSH tunnel. It will get your hopes up, letting you get to the server and character selection screens, but then won't actually let you sync, since SSH tunnels don't support UDP.
