Hello!

To configure a GUP:

Edit the Liveupdate policy for the group that the GUP and the clients that should use the GUP:

Click ok, and thats it!

To verify that the computer that should serve as a GUP really has got the config, just check it properties:

To check that the clients really are using the GUP, go to Monitor - Logs:

And in the log you should see:

If you are using a firewall on the GUP then the port used must be opened, default is 2967.

Good luck!
