We have a UAG/TMG server set up with SharePoint published. The UAG is also doing load balancing for the SharePoint farm. We have an MDM application that is trying to connect to our SharePoint but our SharePoint is routed through the UAG. The MDM application does not need to be published neither is there any component that can be accessed directly by end users. It is more of a proxy to relay content to mobile devices. It is using 443 and two other secondary ports.
On the TMG logs, we can see requests hitting the TMG over port 443 from the MDM application server. We can also see that it is trying to be routed to our SharePoint but we get the following error in the TMG log:
“Filter information: A request from source IP address xx.xx.xx.xx, user to trunk portal; Secure=1 for application SharePoint of type SharePoint15 failed. The endpoint device does not comply with access policy settings ([%PolicyId%]) for session [%SessionId]”
The source IP is the internal IP of the host running the MDM application. In the UAG side, under the SharePoint publishing rule, for Access Policy Settings we have tried selecting the 'Always' option but that had no effect. It appears like there is a policy blocking communication to SharePoint. Does anyone have a suggestion on which policy or where the policy that is controlling this is located so that we can try to resolve this issue? Thanks.
