Re: Two network adapters on seperate networks problem

I think each system is connected to a local switch with several other
local devices, and then this switch is connected back to a central
large switch/router that implements the access control lists, vlans,
etc. I'm not too clear of the exact topology truthfully.

Can you ask your system administrator?

But, I can
connect to all of the rooms, which did actually surprise me, so
something out there is making it work.

Maybe the network isn't segmented the way you think it is.

Just in case, I changed the
route command to specify the gw 10.9.81.193 for these routes:

/sbin/route -v add -host $ip gw 10.9.81.193 eth0

Is there a way to tell eth0 to use the gateway 10.9.81.193 for all
connections?

route add -net 10.9.52.0 netmask 255.255.252.0 gw 10.9.81.193
route add -net 10.9.56.0 netmask 255.255.248.0 gw 10.9.81.193
route add -net 10.9.64.0 netmask 255.255.252.0 gw 10.9.81.193
route add -net 10.9.68.0 netmask 255.255.254.0 gw 10.9.81.193

You may need to add the interface name.

I didn't see a way to really do that with the route
command. Maybe I don't want to do that anyways, since it is working
now, why push it...

Too true.

10.9.81.192 0.0.0.0 255.255.255.192 U 0 0 0
eth0

This says that the local network connected to eth0 consists of addresses 10.9.81.192 through 10.9.81.255. The working direct routes you added conflict with this statement.
