We're simply trying to catch the CAS server if it falls over and have the load balancer stop sending MAPI RPC to it. Sounds like static ports are the way to go, thanks.
Thanks to others for replies, too.

It’s used to negotiate an rpc connection for a specific service, and that can be any arbitrary unused port above 49152. If you want to lock down the ports on the firewall, you’ll need to edit the registry to force the CAS servers to only use specific ports: http://social.technet.microsoft.com/wiki/contents/articles/configuring-static-rpc-ports-on-an-exchange-2010-client-access-server.aspx From: Sobey, Richard A [mailto:r.so...@imperial.ac.uk] Sent: Thursday, December 16, 2010 11:07 AM To: MS-Exchange Admin Issues Subject: Testing operational status of an Exchange 2010 CAS server Hi all, Does anyone have any recommendations for which port(s) to test on an Exchange 2010 CAS server for load-balancing / operational status? We’re currently using 135 but stopping the “RPC Client Access Service” – effectively killing the server – doesn’t close port 135. SP1 if it matters.
