Exchange 2010 RPC static port access

Hello all. I have a CAS array configured. The F5 exchange 2010 template created a single virtual server for all of my RPC access. I tested all my MAPI applications and things looked good. I then went ahead and ran the exchange 2010 template again and specified the static RPC ports configured in Exchange. As expected, the template created three virtual servers. I tested all my MAPI applications again and Outlook can't even establish access to the CAS array. I have confirmed the virtual servers are using the static ports I configured in Exhange. I also ran netstat on the Exchange servers to confirm the static ports are listening. Is there some additional configuration I need to do on those RPC virtual servers created by the template? Any help would be much appreciated.
