I ran that configuration for 3 years with zero problems(the server
system I used died unfortunately, so I no longer have the config)  

I believe I was running dhclient for my outside interface.  It was a
gentoo system, mostly patched to current.  One thing to check out is if the MAC
address you are using in Windows ME matches the one that you are using
in Linux.  Comcast will only let the MAC addr that it was setup with to
go through.
