> You may also have PMTU problems... That's it! That should have occurred to me, but it sure didn't. PPPoE has an MTU of 1492. If I change the client machine to use 1492, everything works fine. Is there a way around this short of reconfiguring all the clients? I guess the real solution is for ebay to let the required ICMP messages through, but I don't think I'm going to be able to convince them. Thanks for your help, Micah
