This is in my router's rc.conf: ifconfig_bridge0=3D"ether 02:00:00:00:00:01 addm tap0 addm vlan1" ifconfig_bridge0_alias0=3D"inet 192.168.0.1/24" vlan1 is on em0; neither as an address assigned. And if you want to put IPv6 on there, you also have to add a link-local = address to make rtadvd happy, something like: ipv6_network_interfaces=3D"bridge0 gif0" ipv6_ifconfig_bridge0=3D"fe80::21c:c0ff:fe7d:8c50%bridge0" ipv6_ifconfig_bridge0_alias0=3D"2001:470:1f0b:xxxx::1 prefixlen 64" --=20 Stefan Bethke <stb@lassitu.de> Fon +49 151 14070811
