Need help to setup VPN in Windows 2000 Server

Hi,

I'm a novice to windows networking. I need to setup a VPN connection
between two of our office locations. Here is the scenario.

We have couple of client server applications running in LAN hosted on
Windows 2000 /SQL 2000 server environments. We would like to have these
applications accessed by one of our remote offices. Thought VPN might
be a good and cheap solution.

Win 2K server has dual Network cards. Card 1 is connected to LAN from a
router (netgear) and card 2 is directly connected to ISP. Card 1's IP
is in LAN 192.168.2.3 subnet 255.255.255.0 Gateway 192.168.2.1 (router)
DNS 192.168.2.3 (server itself). Card 2 has the static IP assinged by
the ISP with corresponding IP,Subnet,Gateway & DNS. This is the Domain
controller with DNS,DHCP & IIS enabled. All the workstations in the LAN
are connecting to this domain and accessing the applications from the D
drive of the server.

I tried configuring Routing & Remote access as described by Microsoft
guides on Network card 2,but didnot succeed. When I try to establish
the connection, I am getting the error message Couldn't establish
connection.

Then I tried to configure Routing & Remote access on Network card 1
with appropriate ports opened thru the router (1723,500,51 & 47
forwarding to the server LAN IP), but not successful.

Can some one please guide me how exactly I should be setting up the
VPN.

I searched google groups to findout a similar situation and didn't find
much info. I appreciate any help.

Thanks
Ash

Thanks for the reply Robert. You said that it is not recomended to use
DC as a router right. What could be the impact if I use DC as the VPN
server? Can you please give any information about the possible problems
by doing so?

Incase, if I cannot have other server and want to use the DC as VPN,
can I still do that?

Please advise.

Once again thanks for your reply. I really appreciate this.

In addition, VPN is not usually a good solution for database operations.
The latency of a VPN connection often gives you poor performance. Terminal
services (where the app runs on the same highspeed link as the database
server) works better.

Bill has a good point. So, you may do TS over VPN.

Thanks for the reply Bill,

As we have over 10 users and we don't have that many TS licenses, we
thought of going with VPN. Anyways, Thanks once again for your reply
