I have tried to set up two different EoIP tunnels over PPPoE links in two different scenerios, and in both cases, I can ping any website in the world from the far end of the tunnel, with DNS resolution through the tunnel, but browsing the web does not work. Our backhaul uses a both public and private subnets, and I am attempting to bond an RB532 PPPoE client's Ether1 interface directly with our backhaul. All of our backhaul links to and from each tower run through EoIP tunnels in every direction, with all of the EoIP tunnels terminating at each tower bridged into a common bridge. The bridge itself is assigned the tower's backhaul IP address. This works very well, each tower having a bridge interface that is it's part of the backhaul, and now I simply want to bridge an additional EoIP tunnel with the others, but this time going over one of the tower's subscriber's PPPoE connections to the client MT. At the client, as stated before, the EoIP tunnel is bridged to the Ether1 interface. This works exactly as expected, up to a point. The client connected to the remote end of the EoIP(over PPPoE) tunnel is directly connected through the tunnel to our backhaul, exactly as I wanted, and this can be easily seen in the ARP table. All traceroutes to anything on the backhaul are one hop, as expected. Finally, as also stated above, I am unable to browse the internet at all through the EoIP tunnel, even though the other EoIP tunnels that this one is bridged with at the tower work just fine. It's just this tunnel.
And then, I cannot ping the Cisco gateway through this specific tunnel, even though packet do route properly through it for a ping or traceroute aimed at the outside. What is even more crazy, is that I can ping an MT router that has an IP address one up from the Cisco and is connected to the same very switch as the Cisco is. I can ping both that MT and Cisco from other EoIP tunnels in the backhaul.....
Any ideas, anyone? Thanks in Advance....

PS- Our backhaul EoIP tunnels run inside encrypted PPTP tunnels, and work very well, so I am wondering if it is not related to the PPPoE, although I would think that the sub-layer(the PPPoE layer) should not affect the operations on the inside of the EoIP tunnel that is running on top of it....
