just consider TUN devices as normal nic interfaces. if i had local lan A = 192.168.0.1/24 (ip address of the nic on the local lan) local lan A openvpn TUN = 192.168.1.1/24 (ip address given to the openvpn tun local lan b openvpn TUN = 192.168.1.2/24 (ip address given to the openvpn tun) this talks to lan a local lab b = 192.168.2.1/24 ( ip address of the nic on the local lan at B) for a machine at local lan a (say 192.168.0.100) to talk to a machine at local lab b ( say 192.168.2.200). I would need a route on the gateway box in local lan A something like ip r a 192.168.2.0/24 via 192.168.1.2 and on the gateway box at local lan b I would need a route something like ip r a 192.168.0.0/24 via 192.168.1.1 you will still need to look at your firewall Alex > . > > Thanks, ...
