VPN and DNS ?

Hi,

I've set a VPN (IKE and IPsec) between two offices via two Dlink DI-804HV
routers.
WAN side, each router has a fixed IP address from my ISP.
The LAN IP addresses of the routers are 192.168.1.254 in one side and in the
192.168.2.254 second side.

I've a server Windows Server 2003R2 SP2 (AD, DHCP, DNS, WINS...) which
manages the Domain for both LAN (192.168.1.0 et 192.168.2.0).
How do I have to set my DNS to allow all servers and all workstations to use
the VPN to communicate between two LAN, and to navigate on the Web via the
Internet access of each office.

Thanks a lot for your help,
Chris

If you only have one DC, all machines must use the DC for DNS. To allow
this DC to resolve foreign URLs you need to set the local DNS to forward to
a public DNS service.

Each workstation should use the DC for DNS but use its local router for
its default gateway. That should be all you need to to. The routers should
automatically send traffic for the "other" private subnet through the tunnel
and everything else out to the Internet.
