Why is tunneled packets rejected on host B, if only host A has set up a IPIP tunnel to host B and not viseverse? that is
A ---tunnel--> B and not A <--tunnel-- B
It seems to be required that both host issue the "tunnel commands" for the tunnel to be complete, even if I only want to send packets in one direction, eg A ---> B
I have tried to set rp_filter on host B to 0 but that doesnt help!
