I'm testing KEMP with publishing Exchange 2016 in a 2 node PoC setup, test tool is https://testconnectivity.microsoft.com.
I've created two VIPs for testing based on the Exchange 2013 templates and publish one of them on the FW under a single public IP/DNS name:
- L7 per server: everything works fine
- L7 per service using content switching: RPC over HTTP test fails, all other protocols work fine. The error is the following:
Attempting to ping the MAPI Mail Store endpoint with identity: email@example.com:6001.
The attempt to ping the endpoint failed.
An RPC error was thrown by the RPC Runtime process. Error 1818 CallCancelled
Elapsed Time: 57273 ms.
I see no errors within the KEMP system log with L7 debug traces turned on.
What could be the RPC specific problem on KEMP which comes up only when using per service content switching?
The RPC selection pattern is /^\/rpc.*/ from the template.
