Client could not attatch to the game server (Across network)

[copperm0e]

Server POL 095
Client: 400c Riced Yoko version d/l from link from forum.
Locally, this works just fine on my machine. Have a secondary computer on my home network using the same files. Game loads, gets past login, shows servers and when I try to get past the server it looks for a few seconds and then says "the client could not attatch to the game server"
the LAN ip's should be fine or it wouldn't even gat past the password part. Encryption is proibably good as well since it is configured and working on my server machine that I log onto locally. So, any ideas?

p.s.: Necr0potenc3, If you are reading this then thank you for showing me this web site. A little hard to understand somtimes since I only speak/read english, but this program got the server up and running.
