2006: Publish additional SSL site - run into problems with Web Listener

Single NIC ISA 2006 in a DMZ, ISA Server only has one IP address.

Used the OWA wizard to publish OWA, works like a champ. SSL Cert is
mobile.domain.com. Trying to publish another website that uses SSL,
we have purchased a wildcard cert since publishing OWA, so we have a
*.domain.com installed on the ISA server as well. Trying to use the
*.domain.com cert on the new site's Web Listener. The new website
I'm trying publish does not reside on the same server as the OWA site.
From what I do understand, ISA will figure out which page to send the
request based on the host header.

So, my listeners look like this:

mobile.domain.com
Networks: Internal
Port(HHTP): Disabled
Port(HTTPS): 443
Certificate: mobile.domain.com
Authentication Methods: No Authentication

repnet.domain.com
Networks: Internal
Port(HHTP): Disabled
Port(HTTPS): 443
Certificate: *.domain.com
Authentication Methods: No Authentication

When I try to use the repnet listener I get the following error:
"A Web listener specifying the same port and similar IP address is
already used by rule "mobile.domain.com". The port and IP address
specified in a Web listener cannot overlap with the IP address and
ports specified in another Web listener already used in a different
rule"

So, is this telling me that for every webpage that I want to publish I
have to give the ISA server additional IP addresses in the DMZ? I
know this might sound stupid, but I really don't know much about ISA..
Googling has been little help and the ISA 2004 books haven't helped
much either, please speak slowly & use small words :-)


Thanks..
