You probably want to do: modprobe tun modprobe bridge ifconfig eth0 0.0.0.0 openvpn --mktun --dev tap0 ifconfig tap0 0.0.0.0 brctl addbr br0 brctl addif br0 tap0 brctl addif br0 eth0 ifconfig br0 xxx.xxx.xxx.240 netmask 255.255.0.0 broadcast xxx.xxx.255.255 Since bridging is at link level (2) not network level (3), you should have an IP for the bridge and none for eth0 and tap0. If you need to forward packets but have separate IP subnets, than you want to use IP forwarding not bridging.
