Could you also post a description of your network topology?  Something like:

(ISP) <-> Your Router <-> Possible switch or hub <-+-> The linux box
                                                   |
                                                   +-> Box that works

Mainly, just need to know which box does NAT or if you're swapping 
cables so only one box is on-line at any one time.

Cheers,
Dave
