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
