Using https://join.me/ thru the web gateway don't work.
I am using the basic Share your screen function.
The download the client function works but when it starts the connecting box it never connects.
If i put my workstation in the firewall with any/any access I get connected and get the join.me/xxx-xxx-xxx number.
The problems isnt that it doesnt work through the MWG, its that it doesnt go THROUGH the mwg. The application must first abide by your proxy settings. So there isnt much that can be done on the MWG.
