Looking for configuration suggestions for this setup. Say you have one ASA 5520 that is your company uses as it's default gateway for internal clients. Say you get a second test ASA 5505 to test certain features, etc... You want to use the second "test" ASA as the default gateway (to the internet) for a single particular vlan inside your network although this vlan still needs to be able to access internal resources. The only difference will be that it uses the "test ASA" as its default-gateway. Could this ben done with an access list, and route-map by specifying the internal (in side) address of the test ASA as the set next-hop? We already have the basic ip connectivity from the vlan to the "test ASAs" internal interface. We just need some direction on the routing portion. The internal vlan subnet you use for the ACL would direct external traffic to the test ASA? Does this sound right?
Yes you put the ip policy route-map command on the VLAN interface where the traffic enters the router that you want to send to the test ASA. And it would be logical for it to use a standard access list in the match statement to identify the traffic coming from the PCs in that VLAN.
That link looks like a pretty good one. I am glad that you found it.
