Hello, I am trying to implement a Broadcast GRE Tunnel that is described at this link http://linux-ip.net/gl/ip-tunnels/node9.html but it doesnt seem to be working.
I am seeing the GRE packets for both networks on both sniffers but the
tcpdump i tun0 doesnt show any of the packets from the remote end
getting there.
Can you tell me if I have something misconfigured or if what I am trying
to do is impossible.
Ive listed all the configuration information under the ascii drawing
Basically trying to get routing information from network A to network B
without knowing what the ip address is for remote eth0 is, hence the
multicast address, and keeping the overhead as low as possible.
Thanks.
