Firewall/Router

[Julio Gutierrez]

I'm trying to setup a router/firewall for my little network,
and I think I need help finding out what daemons I need in order to make it 
work, I don't need any graphical desktops or even X I want to 
administer from console.
I'm trying RH 7.1 because is the only distro I've been able to setup & run on 
this PC, this is a P75 IBM 64MB RAM 514MB HD. 
can someone can lead me in the right direction or tell me how to do this?
your help will be greatly appreciated!!!
