How to set up a local update server (YOU Server)

Hello, I have several servers with access only to a local network and on not to the web in general. I was wondering if it is possible so run a local update server (on open SUSE 11.3 desktop) on a machine with outside access and have the servers with only LAN access update using that machine. If this is possible can someone point me to a HOW TO or just tell me if there is a configuration panel in YAST2. I have found in google mentions of a YOU server in SUSE10 but cannot find this in 11.3
