Hello all!

I have test infrastructure with one frontend server in a pool and one edge server in internal network.

Also I have one TMG server, which is connected to internal network and DMZ with a second NIC.

External address with port 443 is natted to DMZ address interface port 443.

Task is to publish Lync IM to be available to external users.

I read lots of articles how to publish IM to external users. Nothing works. Do I need Edge server for my needs?

TMG show only unidentified traffic 4443 in logs, nothing works.

Could you please describe the procedure step-by-step how to publish Lync IM to external users please.

Thanks in advance.
