We just recently added a second backbone connection for a customer, but
are having some problems with the routing.  Here's how it's setup.

T1A comes from provider 1 and is connected to a Cisco 2501 which is inturn
connected to a switch.  T1B comes from provider 2 and is connected to a
Livingston OR-HS.  T1A is the default route for all machines on the
network.  The trouble is that we've got a FreeBSD box with 2 10BT ethernet
ports on it.  the first port is connected to the switch that the 2501 is
connected to.  the second port is connected via a crossconnect cable to
the Livingston OR-HS.  When we try to ping the 2nd ethernet interface (via
T1B) we don't get a response.

I assume that the problem is caused by packets coming in on the 2nd
interface, but that the default route on the box points to the 1st
interface and that's where the packets are going out of to get back to the
originating host.  Am I right?  Is there a way to get around this, or do I
just need to setup another box dedicated to this one T1?

Thanks in advance...
