I tried searching the list archives, but every search returns "nothing matched", I think 
search is broken.

I have two RH 7.1 systems, one with Dynamic IP, both behind firewalls.. They can 
connect and I can ping the peer address from each end, but I always get duplicate 
packets.

That is, in either direction, the ICMP reply is DUP!. Of course, it could be that the ICMP 
request is duplicate. Traceroute -vv always shows 0 as the id, so I can't really tell which 
end is duplicating, or if the duplication is happening in the cipcb driver during decoding 
and not on the wire.

Watching the encrypted udp packets, a ping of 64 bytes results in a 104 byte UDP 
packet being sent, and there is always one encrypted packet sent for each reply and 
request.

Has anyone seen this before, how do I debug it?
