I am trying to set up some of our ADSL Routers with GRE Tunnels but some will not work. On the routers that do not work, the normal ping will does not work to start with. I can ping using the extended ping feature, but a straight forward ping does not.
Other routers where the ping works, the GRE Tunnel works straight away.
Anybody got any ideas?
Beside believing that its a routing issue from the destination, it might be a routing issue within your provider kindly consolidate with them.
