[GRLUG] Routing Weirdness

[L. V. Lammert]

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

*Most* of the time everything works fine, but randomly, traffic from the
remote site gets routed through the Main site route to go out! 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.

And will stay bad for a while. Try again in a few hours, and it's back to
normal.

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!
