Installing and configuring a clustered Sametime 9 Gateway to use instant messaging with external communities using a DMZ XMPP proxy and a DMZ SIP proxy

This paper describes the procedure for installing a cluster of IBM Sametime Gateway Servers in a network deployment to allow internal Sametime communities to communicate with instant messaging communities that are hosted outside of the intranet.
