Cisco 2620 Configuration with two T-1's
I need a little help with a (at least I think it is) complicated problem - I have two T-1's that are "terminating" into a Cisco 2620 router. Each LAN port on the 2620 then goes into a port on a PIX 515. A third ethernet port on the PIX is connected to a switch serving two LAN's. (Each LAN has a DSL modem bridging the LAN to the "WAN" that the PIX plugs into.) Unfortunately, the PIX can only have one default route; and the default route is the only way I can get the PIX to pass traffic to one of the T-1's (to get to the internet).
What I want to do is have the PIX (without performing NAT) pass traffic to the 2620 and then have the 2620 Router send it to one of the two T-1's based on the source of the request...and then NAT the address on the way out the door.
Has anybody tried this before?
The Network IP's are as follows -
T-1's = 68.152.249.x
PIX Addresses = 68.208.63.x (from Cisco ports to PIX) & 10.10.10.100 (from PIX LAN to switch).
Two Networks = LAN's of 192.168.102.x & 192.168.125.x - their "WAN" address are 10.10.10.105 & 10.10.10.205

Can you provide a diagram of your network? I'm having a little difficulty wrapping my mind around it.

2 T-1's -----> Cisco 2620 -------> PIX 515 (each ethernet port on the 2620 has a corresponding port on the PIX)
PIX 515 (third port - true "inside" interface) inside IP is 10.10.10.100 -----> Catalyst Switch
Local Area Network #1: LAN IP 192.168.125.x ---> DSL router. The DSL Router has WAN address of 10.10.10.105 & Gateway of 10.10.10.100 (PIX)
Local Area Network #2: LAN IP 192.168.100.x ---> DSL router. The DSL Router has WAN address of 10.10.10.205 & Gateway of 10.10.10.100 (PIX)

Routers
A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
