Hi Guys!

Dragging up this old thread again, because 'implementation day' is quickly approaching, and I'm trying to cover as much theoretical ground as I can...

I finally decided to do the VPN tunnelling via Draytek 2800G DSL routers, which should be very much up to this task.

Now, this is probably a stupid question to you expect users our there, but here goes anyway...
Trying to do the following: setup a VPN between two Draytek 2800G routers, obviously in a different geographical location.

I've read the VPN LAN to LAN FAQ here, and I understand what it says. There's just one thing that puzzles me.

The FAQ says : it is essential different subnets are used for each connecting network. I understand this, and also understand how and why this would be necessary. However, do I need to setup this subnet somewhere in the router's web interface? And, if so, where? (see this DrayTEK routers webinterface HERE)Of does the subnet simply follow the IP subnet the router is set to??

Eg. it should be something like this:
Location 1: 192.168.1.0 (= subnet)
Router IP : 192.168.1.1
subnetmask : 255.255.255.0
NAT IP range behind router: 192.168.1.50 to 192.168.1.100 (which means 50 devices can be connected to the router, which should be MORE than enough)

Location 2: 192.168.2.0 (= subnet)
Router IP : 192.168.2.1
subnetmask : 255.255.255.0
NAT IP range behind router: 192.168.2.50 to 192.168.2.100

Now, my back to my question: I can setup the router IP, I can setup the subnetmask.... but where do I setup the subnet itself?? Or again, will it simply follow the subnet I choose with the router's IP?

Thanks in advance!
