If there is a specific reason to use VPN, we get that resolved. But if you only need remote control, LogMeIn offers a free solution and is very easy to setup:

Any computer/server/router/etc on a network can only have one default gateway. If a Windows 2003 server is hosting Routing and Remote Access (RRAS), and has a NIC that connects to the internet (even if it's NAT) - then the internet NIC (or VPN nic as you labeled it) has the default gateway. The NIC that connects to the LAN has no default gateway.

DNS can be your ISP DNS, whatever that is, or a local, internal DNS server if you have one - sometimes it's the IP address of your router (if the router supports that).

Good reading:
You have two options using W2K3 - PPTP or L2TP. You might want to consider PPTP since this doesn't require certificates.


    To allow PPTP tunnel maintenance traffic, open TCP 1723.
    To allow PPTP tunneled data to pass through router, open Protocol ID 47.

L2TP over IPSec

    To allow Internet Key Exchange (IKE), open UDP 500.
    To allow IPSec Network Address Translation (NAT-T) open UDP 5500.
    To allow L2TP traffic, open UDP 1701.
