Hi Walla

Have a look at MTU as well - I have seen this before and the Telco had
chaged the MTU of the carrier network. I tested with extended ping and
different sized packets.

Okay, well I learned from your replies, so thank you.

But, as far as routing, I CAN ping from A Lan to C Lan right though the
B
router... Just not telnet.

I feel like it is an ACL or Firewall somewhere but there are not any
that I
can see or have been told about. Also, None of the routers have ACL's
applied. Is it possible that they have some legacy ACL floating around
in
their configs that is not showing up on the saved and running configs?

How would I clear that sort of possiblity short of rebooting all of
them?

Thanks.
