MS TMG - Lync, OWA & Exchange ActiveSync

I'm having real issues trying to allow access to Lync, OWA & Exchange ActiveSync from an external client through MS Forefront Threat Management Gateway 2010.

The issue is that they all want to listen port 443, and as I have a Cisco router I can only forward port 443 to a single internal IP address.

I can get Lync working, or I can get OWA & ActiveSync (AS) working, but not both at the same time because OWA & AS require 'HTML Form Authentication' whereas Lync requires 'No Authentication' (on the listener).  As as I can't create two listeners both listening on the same IP and same port number (with different authentication levels) I'm a bit stumped.

Any ideas??

It's ok, I seem to have resolved my own issue.

I created one listener for all published rules (with a wildcard cert).  I set the authentication to 'HTML Form' and then set the 'rule authentication' as follows:

Lync - no delegation, but client may auth directly
OWA - basic auth
AS - basic auth

and now all seems to work :)
