How to use two T1's from different vendors.

[AV1611]

I have a Bellsouth T1 and an Xspedius T1. Both of these come into the same facility. I have 3 switches that hold all my connections to the LAN. This is connected to a Firewall that is connected to the Bellsouth T1. I want to divide my traffic, or pick certain traffic to go out of one T1 and certain traffic to go out the other T1. How can I do this and keep it all on the same LAN. Is it possible to just use another Firewall between that T1 and one of the switches and have some machines with one Gateway and some other machines with a different Gateway. And if this is the case would I have to log two different Gateway's into my Windows 2000 Server? How can this be done?

Let me ask this. Whats doing the routing, most switches and firewalls do not route. If you had a router in place you could send traffic from certain IP ranges through either T1. Just curious. I hope this helps and let us know.
