home multipurpose gateway/router/server setup help

[Moisa Teodor]

Hello,

I wanted to set-up a multipurpose server/gateway/router with an old pc, but
ran into some trouble.
I have an internet connection from a local ISP (it's not cable or adsl it's
ethernet) and a couple of home computers. The ISP has a
litle program that needs to run continously in the background (it connects
to one of my ISP's servers on port 2400)
If that program does not run, i cannot go through the ISP's gateway.
In the past i had another box with smoothwall linux, but the motherboard
crashed. Anyway, on that box i was able to
do the trick.
I have installed FreeBSD. Both network cards are working (sis0 and pcn0). I
runt the ISP's software and i have internet
access. Good. But i want to shre this internet connection with my home LAN.
I read somewhere that i need to recompile
the kernel and enable packet filtering and firewall (the tutorial i used is
located here http://www.lugbe.ch/lostfound/contrib/freebsd_router/).
However, when i reboot with the new kernel I cannot connect to any network,
neither the ISP's nor my home LAN.
I want to use this box as a gateway/router/firewall for my home lan, and
also run some services like a web server for my projects, etc.


Thanks a lot for your help, and keep up the good work
