Then you select "802.1d Ethernet Bridging" and "netfilter (firewalling) support" when configuring the kernel. You need to download the br-nf patch and patch the kernel source with it. It is available at: http://bridge.sourceforge.net/ The file you are looking for is: http://bridge.sourceforge.net/devel/bridge-nf/bridge-nf-0.0.7-against-2.4.19.diff The documentation I successfully followed to build a transparent filtering bridge with a 2.4.x kernel is: http://www.think-future.de/DOCUMENTATION/Ethernet-Bridge-netfilter-HOWTO/ I browsed other documents, and found another well-written one that covered the initial steps well, but when I tried to bring the bridge interface up using those instructions it failed. The above link's approach worked painlessly, and it took about 25 minutes from download to a working filtering bridge, which now sits between an ISP and the internet. j
