Cannot see any available IP Address/Trusted certificates when creating a web listener

Question 1

I am installing Forefront TMG in a lab on a unihomed server and I want to create two publishing rules for two different Exchange Servers. The NIC has multiple IP addresses bound to it, however when creating the listener I do not see any of the IP addresses. We use to do this configuration in ISA 2004 and 2006 but I don’t know how to solve this using TMG, do you have any ideas?

Question 2

I created a self signed certificate on my Exchange servers (using IIS) and exported them to my TMG server into the “Personal\Certificates” and “Trusted Root Certification\Certificates”; however these certificates do not appear when I am trying to create a Web Listener?

Thank you, DM
