Hi,
I currently have two gigabit ethernet cards in which i want to bridge together to have traffic flow through in which would also be filtered via iptables. Any suggestions creating this firewall? Anyone know of a good tutorial?

There is plenty of iptables docs out there, I suggest firehol It was very easy to set up and has been running great for many months now.

The Gentoo Home Router Guide may show you the steps needed for ipforwarding between the two interfaces and also a lots of other tips for building your firewall.

Another quick way to build a dedicated firewall are to use one of the specialized distributions like IPCop or Smoothwall. Setting up ipcop will take you about 15 minutes or so, and you'll have a complete firewall with ipforwaring between interfaces, IDS, VPNs etc.

If you have the time and interest I think that building a hardened Gentoo firewall is an excellent choice, also for the learning experience. If you are more in need of a quick and simple yet pretty customable solution, than IPCop/ Smoothwall are great choices that even work well for old hardware.
