Single GUP Configuration

Hi to all,

I want to configure a client to apply Updates to workstations of a group away from Central Offices because every morning it takes a lot of bandwidth.

Here is the scenario:

I have two offices: OfficeNo1 and OfficeNo2.

SEPM is installed on OfficeNo1. 

I have create a group for OfficeNo1 and a group for OfficeNo2 and add the workstations and servers to the right group.

Then i have select a server from OfficeNo2 (which is on the group OfficeNo2) and i have configure as a Single Group Update Provider by adding the ip of the server.

Also i have chenge the LiveUpdate Policy fro group OfficeNo2.

After that clients of OfficeNo2 are still getting updates from SEPM from OfficeNo1.

Am i doing something wrong?

Thank you
