Subnets and VPN

We are getting ready to open a new remote office and I have a few
questions regarding data.

Here is what we have:

Headquaters
Cisco Pix 506e
DHCP is dished out through Win 2k3 RC2
IP Range 192.168.1.x

Remote Office:
Cisco Pix 506e
DHCP is dished out through the Pix
IP Range 192.168.2.x

We will have site to site VPN setup through the 2 Pix routers.

Now my question...
How do I get the 192.168.1.x and 192.168.2.x to talk to each other?

I am thinking that since the VPN is create a virtual connection (and
thus a virtural IP for each macchine) that will be all the routing that
needs to be done. All of my 192.168.2.x machines will be able to see
all the 192.168.1.x machines (pcs, servers, etc.). Is this correct?

The reason I think this is because right now we have remote users (not
on a site to site) using the VPN software from Cisco and when they VPN
in to the headquaters they are able to see everything (no matter what
local IP they have on their machine). The Pix and VPN software give
the remote user a 192.168.11.x virtural address, but they can still see
the 192.168.1.x machines.

So am I correct in thinking that the site to site will do the routing
so the 192.168.2.x can see 192.168.1.x and vice-versa?

Thanks,

Ron

Correct. The Cisco site to site VPN will let you route and access each.
