Fix bridging interfaces

Bridging between interfaces work. Tun device ip address and ip routes must manually be set after starting the program using following commands: (ip address must be changed to match network)
ip addr add 213.233.168.32/22 dev mytun
ip route add default via dev mytun

Note: Ip packets aren't forwarded to tun device. Applications recieve packet on phyical device even thought packet was sent on tun device.
