Without wanting to start a flame war, for what you have described I would use OpenBSD, not FreeBSD. OpenBSD has an excellent track record for security, and it comes with a built-in firewall called "pf" which is highly configurable and allows all manner of traffic manipulation. OpenBSD is free to download and runs on many architectures including i386 and sparc. To enable routing on an OpenBSD box, read

Can you clarify your network config? Is it really:
INTERNET -> Modem -> Hardware Firewall -> New Firewall -> LAN ?
If you're going to be doing any hosting or public access boxes (e.g. web server) these should be situated between your two firewalls in a DMZ or alternatively hand off a seperate interface.
