DHCP over VPN - new DHCP scope question

I have a VPN which is set up to link a head office with a branch office.

Our DNS server at the head office has an IP of
There is a DHCP Scope that has a pool that allocates the range - to clients.

Our VPN router has an IP of

I have set this up very simply - VPN router to VPN router across the internet.

At our branch office we have NO DHCP server. Our VPN router is allocated an IP of

I would like our clients at the branch office to be allocated an IP by our DHCP server at the Head office in the range 192.168.16.x when they boot their machine. I have configured the routers correctly to allow this but have been advised by the routers manufacturer that I will need to add an additional DHCP pool to the server to allocate IPs correctly.

The router I have used are a pair of Draytek Vigor 2830n.

Can anyone help me with the DHCP configuration on the server?

Have you considered using the DHCP server function built into the Vigor 2830n? That would allow you to assign IP addresses directly at the branch office.

You can not use same network IP addressing on both sites because traffic can not be routed between sites. Branch office must use 192.168.60.x network.
But, you can configure new scope on you existing DHCP server with this network (192.168.60.x) and configure helper address on your VPN routers to let DHCP server lease on remote site.

Then I would have two DHCP servers on the same network allocating a similar range?
I would like my remote clients to be on the same subnet as my head office clients.
