That would be consistent. It could be either end that expired.

Do you have routes for the 199.78.xx that are disturbing the set up or
is the client setup cleanly updated all over.

I think you mean .255 - I assume thats a typo

The big red switch is always worth trying. I've certainly had 3com kit
I had to do a full database erase on to get back to sanity when altering
routes. I thought bay was better quality tho

The Linux boxes can handle your network description fine for Linux 2.0,
you can put 256 different networks each with a variable subnet mask on
each host. If you need more than that boy have you got a freaky network

It'll do it but badly. You want PCI for a loaded 4 or 5 port Linux router.
The cogent boards are one option. You can run a less loaded network on ISA
(We've got a firewall/router that runs 4 10Mbit networks on WD80x3 cards
and 3c509's over ISA).

It sounds like one a bit of tcpdumping and use of off switches will find
fairly fast
Good luck
