Exchange 2013 SSL Offloaded with Re-encription and BES 5

Hi,

We have a two Exchange 2013 servers load balanced with ssl offloaded and traffic re-encrypted at L7.

This works perfectly, however our Blackberry Enterprise Server 5.0, will not communicate via the VIP.

If I use a host file on the BES server to bypass the VIP and point it directly to an Exchange server it works just fine.

BES support told me its an issue with the load balancer configuration, but I'm struggling to find what it could be.

Any help would be greatly appreciated.

Many Thanks,
Chris

I would suggest running a TCP Dump to capture what is happening - https://support.kemptechnologies.com/hc/en-us/articles/200539529-TCPdump-Tips - you should then be able to filter based on the source IP of the BES server to see the traffic arriving at the VIP on the LoadMaster that handles your Exchange traffic.

Also please indicate what version of firmware you are running.
