Netgear BR500 Site to Site VPN with AD Doman Network

Good Morning,

I have a client who has moved into a serviced ofice, but is acquring a temporary site to host his printing operation.

I have recently set-up a new Server 2019 domain with all his machines (Windows 10) connected to the server.

Looking at the Netgear BR500, it appears to create a direct site to site VPN.

If I was to move a couple of my machines which will be a coule of macs and a few windows 10 PC's to the new site will these domain joined machines, still be able to access the A/D Server and its resources at the primary site.

The new site will only have two users initially and will be running of an LTE network connection until a fibre connection is installed.

The primary site has a static IP Address for the server, the question I have is do I set up the router and BR500 to use the same network IP but a different range i.e. site 1 would be 192.168.8.1 to say 192.168.8.150  and site 2 would be 192.168.8.151 to 192.168.8.248

The server os set at the 1st site with a static IP of 192.168.8.65

Please feel free to ask questions or seek clarification on the problem at hand.

Any help would be greatfully appreciated.

Many thanks,

Mike
