I have been asked to set up a server to act as a basic ipfilter packet filter/ to sit between our t1 gateway router and some lan devices.
basically, i'm looking to filter the packets coming in on eth1 and pass the filtered packets on to eth0. the caveat is that eth0, eth1, and the lan servers are all using a public static ip range, so there can be no NAT.
what's the best way to bridge the two connections to make this happen? I'm required to do this in fedora 7, and I'm unfamiliar with the tools that could make this easier.
