I'm trying to set up pretty simply configuration consisting of two linux machines connected over tun-interface created by OpenVPN.
The VPN-connection is working fine - I can send data over this interface. Now I installed bird and configured ospf on both devices. I can see that both bird instances are sending hello packets on tun-interface however no one of them is getting the message. I can see with tcpdump, that every device is getting the hello-message. However they are not forwarded to bird or bird just ignores them. I tried my setup over cabel with eth0-interface and everything is working fine. Right now every machine is advertising just one example static network. I will focus on correct advertising later after I connect those two instances. The tun0 interface is working in type ptp and the netmask is 255.255.255.255. Do you have any idea what's wrong? Thanks for every input, tookie009
