11501 OWA HTTPS

[CLIFFORD BECKER]

I am having some issues loadb alancing across 3 servers running Outlook Web Access 2003 using HTTPS. I don't have an SSL module but was given the idea that layer 3 or 4 load balancing might work. When a connection is established to the VIP ip address I can see with a packet trace that the first SYN packet it sent to the VIP but the SYN ACK response is from one of the OWA servers which cause the client to send a RST killing the conversation.

Anyway around this?

Sounds like the return traffic from the OWA server is not passing through the CSS. Can you take a packet trace from the server side of the connection?

Just a suggestion... If the CSS is not the default gateway of the OWA servers, then you will most likely need to add the OWA servers to a source-group as "destination services", and give that source-group an IP unique to the CSS. The user source IPs will be NAT'ed to the source-group IP, and as long as your OWA server's default gateway knows how to get to that source-group IP, the reply traffic should flow properly.

I add the group with destination services and that resolved the issue. Thank you very much.
