DOWN WITH DUMB GATEWAYS!

I see lots of similar things (routing) since the core gateway egp tables got
full. What I see happening from lots of hosts is that I receive datagrams
(mostly SYNs or UDP Domain requests to our domain server) to which I respond.
The responses bounce at the gateway since it does not find the entry in the
egp table and sends an ICMP net unreachable back to me. The frequent
retransmissions are a different problem which also showed up in a much
elevated way since the egp problem appeared since I get the data but the
response is not able to get back. We could use this situation as a tool
to find lots of flakey implementation because the retransmission problems
are much more easily visible.
