Hi all,
We are running a single Lync 2013 FE and a single Lync 2013 Edge Server. We don't have a proxy server in the mix.
IM and presence works fine, but we are having issues with screenshare between us and all federated contacts in one domain.
Interestingly, while on VPN its fine, so it seems like its a firewall issue.
Following the http://www.lync-solutions.com/Documents/Lync_2013_protocol_poster_v6_7.pdf I've had the firewall team open up all the required ports, but we still get errors when attempting a screen share stating that network problems are causing it to fail. Looking at the topology builder, I see port 444 as the default port for the web conferencing Edge service, but I can't find any documentation indicating that this has to be opened up through the firewall.
Does it need to be opened from the internet to the IP of our access edge FQDN?
