Cisco ASA - Route Traffic to Specific Interface
I have a Cisco ASA 5510 that is protecting 2 WAN connections for my business (Detailed diagram attached). 1 WAN connection goes to the public Internet. The other WAN connection goes to our corporate network, which also provides access to the Internet
Internally, I use a proxy server to guide proper traffic from workstations to the corporate network, so essentially, all traffic to the corporate network comes from one device. We need to route some Internet-accessible addresses through the corporate network for access-control and monitoring reasons.
What is the best way to force all traffic from my proxy server to route properly over the corporate network interface?
The ASA is running v8.3(2). I have tried a reverse-NAT for the corporate router, access-control rules, and a thousand other things. I'm totally fried and at a loss. Thanks for the help!

seems the solution is for a router, not familiar though if ASA is capable of PBR. sorry about that.

You cannot set the next hop in a route map on an ASA. :-/
Just so I understand... You have traffic coming in the internet router that you want to route behind the corporate router, but still pass through the firewall?
ASKER
No, sorry.
The Internet router will be the default route.
The corporate router will receive traffic that may be Internet-routable as well, which is why it needs to be forced through that interface. We access some destinations which are locked down to the company's Internet gateway, not our local one. This is why I use the proxy server to concentrate all the traffic.
Does that make sense?

The Internet addresses you need to route through the corperate router are they know in advance or does these change?

This solution is only available to members.

It does seem like it since you´d still need to configure the IP route on the ASA as long as all traffic from your proxy and not only the traffic you want to route differently, hits it.
a link below shows a scenario slightly similar to yours
