I've noticed in Debian that sysctl.conf is applied before the if-up.d/bridge script has a chance to load the bridge module. as a result, the sysctl for net.bridge remain the default. i needed to add a post-up to my config to overcome this what is the current setting of net.bridge.bridge-nf-call-iptables? does re-applying sysctl.conf allow iptables to then pick up bridged traffic (sysctl -p)? -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
