Has anyone else seen this? A working bridge running Fedora Core 3 fails after an upgrade to the one of the latest Fedora kernels. What I've found is: kernel-2.6.11-1.14_FC3 and earlier work fine kernel-2.6.11-1.27_FC3 and kernel-2.6.11-1.35_FC3 fail! The problem is with netfilter not with bridging. With iptables shutdown the bridge works fine but even with very simple iptables rules any network connections to/from or through the bridge fail. (Fedora kernels are patched so it's difficult to say which standard kernel version they correspond to but it looks like some new kernel patch has caused or will cause problems with bridge-nf). -- Ian
