Load balancing Exchange 2010 CAS

I have a working setup load balancing an Exchange 2010 CAS on our FortiGate 200B however I have had a terrible time troubleshooting an issue where our email clients will freeze and complain about not being able to connect to Exchange. It eventually finds the server and resumes communication but it is a nuisance for sure. The only reason I am blaming the FortiGate is because I can reboot the FortiGate and the issue goes away for a while. Any ideas?

Hi, AFAIK Load-Balancing Exchange 2010 CAS is not supported. This requires some special feature on the Load-Balancing selection, which only a few Load-Balancers have licensed from Microsoft and implemented! Exchange 2013 load-balancing should be supported with FGT again as it is stateless between Client and CAS server! br, Roman

Hello, Is there any Fortinet statement which approves Microsoft Exchange 2013 CAS Load Balancing via FortiGate Firewall? I would like to setup my Load Balancing for Exchange Cluster via our FortiGate 310B-Custer. Is this possible and tested? Regards

Hello,

 

Is there any Fortinet statement which approves Microsoft Exchange 2013 CAS Load Balancing via FotiGate Firewall?

I would like to setup my Load Balancing for Exchange Cluster via our FortiGate 310B-Cluster. Is this possible and tested?

Or are only FortiADC supported Load Balancers for Exchange? 

 

Regards

Hello,

Same question as above.

 

Do you think it is possible to use Fortigate Load balancing feature ( 6.x )for exchange 2016 CAS high availability ?

( 2 Fortigate 100E configured in cluster ) 

 

Regards
