I have been trying to get a bridging firewall setup with iptables. The iptables part, by itself, is not an issue. I can get it done. My question is: has anyone here ever gotten the bridging + iptables firewall to work? I am using 2.4.19 (I never get anything but 2.4.19 with dmesg or uname -a) with bridge-nf-0.0.7-against-2.4.19.diff for the bridging patch. I am following the documentation provided on bridge.sourceforge.org. I d/l'ed the 2.4.19. Patched with bridge patch above. Made the kernel with iptables support (most options as modules), "8021.d Ethernet bridging" and "netfilter (firewalling) support" included. Everything compiled and installed without errors. I added the interfaces to the bridge interface per the directions. Set all ip addresses to 0.0.0.0 promisc per the directions in the documentation. The default rules for iptables are allow for input, output and forward (forward is the only one of importance). At this point, I cannot get any devices on the 'outside' of the firewall to reach anything 'inside' the firewall. Since all the rules are accept, it should work. I get the feeling the problem may be with the bridging portion. Anyone gotten this bridge + firewall to work? Thanks, Pete
