Router/firewall help

[Mike]

I want to setup a stand-alone router/firewall using the latest Fedora 
distribution. I re-built the kernel and modules, however I can't seem to 
find any current references on how to setup the rest of the system to 
function solely as a router/firewall.

This is probably a different resource, however I will ask: I want to put 
the system on a flash and boot from it. Since flash is painfully slow I 
want to run the system from ramdisk. Any direction on that front would 
be also appreciated.

If this is of interest to others I will publish what I did to make this 
work. The computer is a lightweight board; low power with no fans, 512mb 
DRAM, two Ethernet chips, USB and a bootable 1GB flash.

If someone could point me in the right direction I'd be grateful.
