I am in the process for setting up a fairly complex firewall, that has 5 nic's in it. (one build on + 4port Dlink card) The basic setup is going to be the office on one, Charter Cable on one, Astound Cable on one, and our wireless gateway on the other (the wireless gateway is a Linksys WAP+router+4 port switch). We dont need to load balance the internet connections, but I need to be able to freely switch the default gateway between the two (and we may be adding a 3rd soon too) Can I have some suggestions on how to configure this? Both iptables rules and generic policies would be great. Right now I have a very basic setup, but I know there are some problems with it (being able to route between the external interfaces, and the WAP without much security to name a few) Most of the firewall solutions out there only work for single internet connections, so I will have to do most of this by hand, I assume.
