I am currently trying to set up router/NAT on my Slackware 9.1 machine using 2.6.4 kernel. I am going through NAG2, IP Masquerade-Howto etc. (Not completed yet). Anyhow, as I have to configuring my kernel, I came across Ethernet Brigde Tables which is a sub group of Network Packet Filtering. What is the difference between Ethernet Brigde Tables and IP Tables? Do I need it? Does it offer better performance then normal IP tables? If yes, where can I get help to do it? Or better still, tell me how to do it.
Thanks in advance
