Thanks. We'll let you know when a new response is added.

It is likely that you will need to reconfigure the VPN devices at both ends to reflect the new subnet, and include it in the traffic that needs to be encrypted. You will also need to change the routing at the central site to include this new subnet. Once this has been done, then reset the VPN connection, and see if traffic now passes.

If it is still not working, please post additional information here.
