Hi vmwaredownload ,

User can connect to connection server / security server with both fqdn and ip address. This is the initial session where user authenticating is done.

While launching  desktop with pcoip protocol, another connection is initiated between view client and CS/SS using PCoIP protocol. This connection uses the values provided in 'PCoIP external URL'. Since PCoIP doesn't support communication using fqdn, the 'pcoip external url' always should be IP:port and not fqdn:port.

Refer the document and video by Mark Benson for information on how to configure load balancing. http://communities.vmware.com/docs/DOC-14974

Hope i'm clear this time.
