Is it possible to connect a 515e with DMZ to two service providers? One in the outside interface and the other in the DMZ interface? If it were a router I could enable a dynamic routing protocol and talk to service providers to do the same, but it's the first time I'm supposed to do it with a pix and I'm not sure if it's possible. The idea is to always have an internet connection, even if one of the service providers go down.
You can't do this on the PIX, cause you have no way of telling whether the return traffic will come in via the outside or the dmz interface, which won't work.
The best way to do this is connect the two ISP circuits onto your router outside the PIX and run a routing protocol on that, then just connect the PIX's outside interface to an ethernet interface on the router.
