Thanks to everyone who responded! Most people pointed me towards me
checking if ROUTED or GATED was turned on which they are not. After I
removed the mysterious routes manually they didn't come back but I still
haven't discovered how they got there. Guess I'll just have to keep an eye
on it.

ICMP updates are probably being sent to your system by one or more routers.
ICMP routing updates tell your system what route to use for future packets
to a
non-local subnet. All routers do this in order to decrease the number of
hops
for your network traffic. If you can, verify that the default route for
your
known default router is not set to something odd. We had this happen 2
years
ago.
To fix the effects of an ICMP redirect message on a Unix system do the
following
as root:
route flush
route add default <mydefault router's address>

Subject: Bad routes appearing in the routing table
I am having network problems with my Alpha 4100 that runs Digital
Unix 4.0E with just 1 network card. Recently some of my users cannot
connect to the Alpha. They cannot ping or traceroute to it. I discovered
by doing a 'netstat -r' that there are incorrect route entries that point to
the Internet firewall. I removed them using 'route delete -net' and that
fixed it but they seem to come back. The only static route I have in
/etc/routes is one to the default gateway.
Is there any process that creates routing entries? How do these routes get
created? Is it dynamic?
Thank you,
