Here is what I have (sysctl -a | grep bridge) net.bridge.bridge-nf-call-arptables = 1 net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1 net.bridge.bridge-nf-filter-pppoe-tagged = 0 net.bridge.bridge-nf-filter-vlan-tagged = 0 net.bridge.bridge-nf-pass-vlan-input-dev = 0 You probably also need to check your iptable configuration.
