Since moving our st server to the dark side of the firewall, into a DMZ, our users inside are no longer able to attend meetings in the web client. When they try to attend, the process stalls at "preparing the sametime meeting room". It progresses as far as "3. Testing connectivity". I have included a screen shot...
I have added, what I believe to be, all the relevant port exceptions but to no avail.
I tried to attend a meeting at the servers console, using user credentials, and this loaded fine without any hiccups.
Does anyone have any advice? I realise that this issue has been posted before by someone else but I did not find any resolution.
If anyone has any help to offer, I would be most grateful.
