Hello all,
I am absolutely no OCS/Lync expert. That said, I have a lot of experience with all kinds of set-ups of all other MS products, and have also setup a Lync 2010 en Lync 2013 environment. But only for internal clients.
I am now in the process of setting up external client connection. So no fancy things like Federation or web-based connections.
What I'd like to have is something like a process flow diagram of the traffic that is needed to make this work.
Why is it not enough to open the FW and NAT port 5061 traffic to the Edge server and port 443 traffic to port 4443 of the FE pool?
I'm trying all day setting up a simple environment, but can't get it to work and all "documentation" just seem to contradict eachother and as such is not very helpful.
Can some please explain the traffic flow and help me in the correct direction?
BTW I do not want to use a Reverse Proxy for this environment, but I am using a rather sophisticated FW, which also NAT's the inbound traffic.
Thanks for your replies.
Regards,
Stephan van der Plas
