It should be configured with a default gateway that points to the internal interface of your ASA and should work without issue.

Do you have any documentation/advice for the setup of ISA behind an ASA? I was thinking the same thing that you explain in your post about security in layers, and am trying to publish owa with ISA as a POC in a single nic configuration (home lab: base ASA license only allows two networks) behind an ASA 5505:
(internet)–>ASA–>ISAOWA

I’ve got owa.domain.com pointing to ASA, PAT 443 to ISA. ISA does not apply my OWA publishing rule, and gets the default deny rule. If I put an allow all HTTPS traffic to ISA on top of that, I will get to the ISA server, but not the published OWA page.

Is it possible to accomplish this with ISA behind ASA using PAT?

Thanks in advance for any light you can shed on this for me, as I’m new to ISA.
