VPN on Private Network

[Fred]

I have Windows 2003 Server sitting on a private network
with Private IPs on both interfaces. How do I configure
this server for VPN access without a Public IP address on
one of the interfaces--is this possible? I found that
once I configured the server with VPN using the Private
IP addresses, I loose internet connectivity. My company
is sharing space in an office building and they have
provided us with our own subnet. Does our host company
need to provide me with a public IP address for my server
or can I configure my server using the private ip
addresses in some manner. What am I missing?

assuming you access to the internet using a router or firewall, you should
be able to setup VPN using the private ip. quoted from

Can't access the internal server when remote client establishes VPN

Symptoms: Two offices are connected using a vpn. Both offices run W2K
servers, RAS & TS. When office A connects to Office B you can not connect to
office A from anywhere except from office B. You can not connect using TS,
or a vpn connection. In order to gain access to office A, you have to
connect to office B, disconnect the client in RAS, then you can connect to
office A.

Resolution: When establishing VPN to the office A, the routing table
changes. To fix this issue, disable the "Use default gateway" on the Office
A VPN server.
