Trying to setup a PIX 515e with 2 external interfaces

Hi there,

To give you the background we are looking to migrate from our current internet provider. Because there are a lot of services running through our current connection my idea was to have the old line and the new line running side by side so I migrate the services over 1 by 1. We have a Cisco PIX 515e which had 3 interfaces: outside, inside and DMZ. I'm trying to reconfigure the DMZ interface to be a secondary "outside" or external interface and called it WAN2. Therefore the cisco would have 1 internal interface and 2 external interfaces.

The config is attached with sensitive info removed. I think the problem may lie with the routing as I I'm not sure what to change this command to...

"route WAN2 Y.Y.Y.Y.190 1"

I've tried

"route WAN2 Y.Y.Y.Y.190 1"

but the PIX won't take this as there is already a route setup.

Can anyone offer any suggestions with this? Is it even possible?

Hi Huw,

Unfortunately, the PIX does not support 2 default routes being used simultaneously as you noticed. You would have to use 1 default route pointing to an upstream router that supports policy-based routing, and allow the router to make the decision about which ISP to use.

Hope that helps.

Thanks Mike. I will look at alternatives.
