Connecting Lync Client to Lync Server throw the Internet - Just one StandAlone LyncServer
Hello
I configured a StandAlone (Standard) Lync server 2013 inside my network and I can use the Lync clients internally without any issue, it Works very fine.
Now I want to connect the Lync clients from the Internet. I published my Lync server from the Internet opening ports TCP 443 and TCP 5061 in my router, but when I try to connect from the outside the Lync client returns a generic connection error
Additional information: My Lync server is using the Lync certificate from an internal CA that is trusted by the computers that I want to connect from the outside (It was added to the Trusted Root CA Authority" store in order to avoid certificates issues)
Any idea what is going on?

Hello Cliff,
If I want to add an additional Edge server in order to convine it with the StandAlone Lync Server. Do I need to modify the Lync Topology again? Or just install a new server including that role?
In another hand, what is different that it connects internally in the network but not from the outside?

You will have to update your topology. And as far as the differences, it stems from the media channels that Lync uses and various NAT traversal mechanisms. Like I said, you can read about SIP, TURN, STUN, and ICE in various SIP forums. Asterisk, 3CX, and various other SIP based products use similar topology technologies for the same basic reasons.

The StandAlone Lync server includes an internal Edge component. Is it necessary and mandatory to use one additional server (two servers in total) just for publishing IM for few users?
