TMG filtering access to Webex and GoToAssist services
We have our own non-RBC Internet connection, and use a Forefront TMG box with the web protection service (amongst other bits) for filtering and logging of outbound Internet requests.
We also rely on support contracts with Capita (for SIMS) and PS Financials (for our finance software) that use the likes of Webex and GoToAssist remote-control services when support agents need to provide assistance.
None of them can be got to work - despite the access rules on the TMG box allowing the use of traffic on ports 80 and 443. I've even defined specific port allowances (such as 8200) as listed on manufacturors websites, but nothing I do seems to make any difference.
I suspect TMG's packet inspection mechanism might be getting in the way but TMG isn't really logging anything about the client's attempts to initiate a remote support session, beyond the occasional "connection reset by peer" error code in the web proxy log (10054). And although that's a start, it's not much help!
Does anyone have suggestions as to where the problem might be? Or even have a similar TMG setup, using similar remote software successfully, and wouldn't mind talking through their configuration - via PM or on the phone if you feel more comfortable - so I can sanity-check my own?
Thanks in advance!

Its an msi at least but certainly if you have any more issues its worth a try especially with older apps.
