MS TMG - Lync, OWA & Exchange ActiveSync
Posted on 2011-10-12
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.
