I have a linux server. I have two internet connections from my lan. A t1 and a 768/768 dsl. On the t1 side I have a cisco router and a pix with a static ip for the linux box, so it can be accessed from the outside. On the dsl side I have a dsl bridge (modem) plugged directly into another pix. The dsl side also has a static ip for the linux box.
Right now the linux box is on the t1. How do I get linux to use both connections? If I try to ping it from the dsl from the outside, it send the request back through the default route (t1).
So what do I need to run to make linux smart enough to send packets back the way they came?
