[Cialug] Routing Weirdness

[L. V. Lammert]

OK, .. we have two RVN042s onsite, and there is a wireless link between
one (192.168.1.n) and a remote site (192.168.2.n) so remote users can
access the server (192.168.1.145).

Most of the time everything works fine, but, randomly, normal traffic from
theremote site gets routed through the Main site! For example, these
traceroutes were done in sequence:

Tracing route to ds-any-fp3-real.wa1.b.yahoo.com [98.139.183.24]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  192.168.2.254
  2     1 ms    <1 ms    <1 ms  96-35-167-37.static.stls.mo.charter.com

Trace complete.

Good one!

Tracing route to www.google.com [74.125.192.99]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  192.168.2.254
  2     2 ms     2 ms     1 ms  192.168.1.254
  3     2 ms     2 ms     2 ms  24-182-144-137.static.olve.mo.charter.com

Trace complete.

Next one is bad!

Tracing route to ds-any-fp3-real.wa1.b.yahoo.com [98.138.252.30]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  192.168.2.254
  2     1 ms     1 ms     2 ms  192.168.1.254
  3     3 ms     2 ms     2 ms  24-182-144-137.static.olve.mo.charter.com

Trace complete.

Try again in a few hours, and it's back to normal. Try again after that,
and it's back to FUBAR.

Has anyone ever seen weirdness like this? Any thoughts on possible issues?
The machines with problems are all XP, and my working theory is that after
using a program on a network share (192.168.1.145), XP wants to use the
192.168.1 network for some strange reason, but I have not been able to
prove it.

	TIA!
