Re: network setup question
Thanks to all who replied. I'm starting to zero in on this now.
A few more details:
To follow up with a few more details:

datacenter's router
The hub is a basic $40 gigE switch (not switch/router) from datacenter.
The netblock assignments are:
-------
Your rack space had been set up and your IP block is 207.154.13.32/27:
gateway: 207.154.13.33
netmask: 255.255.255.224

The traffic is definitely going through the datacenter's router
(207.154.13.33).
I'm thinking that adding something like:
server 1: route add -net 207.154.13.128 netmask 255.255.255.244 dev eth0
server 2: route add -net 207.154.13.32 netmask 255.255.255.244 dev eth0
would keep the traffic from reaching the big router, but this is where
I'm just a little shaky on how everything works.
One of the machines is a production machine, so I want to be fairly sure
of this before starting to play with the routing table.
Any more comments?
And... anybody know if the "route" command persists across reboots, and
if so, where it store the information?
Thanks again,
Miles
