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?
