Connecting multiple lans by VPN
Our customer has about 10 different offices.

Head office has a router which maintains IPSec VPN connections to all of the site.

Each site has their own IP range, eg..

    192.168.50.x
    192.168.60.x
    192.168.70.x

What we want to do is connect a router at our office to their head office site via VPN.

Once we have done this, should we have access to all of the other sites connected to the head office?

We've managed to get the VPN connected, but at present can only seem to ping/connect to head office's router and computers.

Is this a configuration thing, or are we using the wrong type of VPN?

I know with a PPTP VPN we would be able to access the entire network, but the head office router does not support PPTP.
