PC DC Server woes and problems

Hi,

I use to have a pc dc server setup on my old xp machine ( which has long been destroyed ) and decided to do a new one on linux...

I'm running ubuntu 10.04 with a intel536 modem and can successfully connect and browse the web using a planetweb disc however IF I try to connect to sylverant ( using codebreaker and my pso disc ) it connects but gets stuck at "Now sending user name and password".

Any ideas on how to get this to work?

Thanks

edit:

If it helps to understand how the network is setup...

dreamcast -> pc ( pc dc server ) -> router ( wireless repeater bridge ) -> router -> broadband

can you post your mgetty logs?

try opening these ports on your router..
