Really hoping to get some help here, as I'm stuck.
We have TMG 2010 installed on our system and all of our users' web browsers are configured to go thru port 8080 for both HTTP and HTTPS traffic on the TMG server. The rule allows access for authenticated users - the traffic then gets routed through Google Postini for web filtering.
I'm installing a new Linux-based backup server that needs access to inbound and outbound traffic on ports 22, 123, and 143 (for off-site backups). It also needs HTTP and HTTPS access. It can access HTTP pages, but I'm getting an error when trying to access HTTPS
: SSL received a record that exceeded maximum possible length.
This condition is repeatable using a Windows laptop plugged into the network - :80 works fine :443 doesn't.
Is there an easy way to configure the server to pass straight thru TMG? The vendor states that the product does not support using a proxy server.
Spent a couple hours on the phone with support with no resolution on this :( can anyone here help?
