Setting up VPN using Windows 2000 Server

[Bill T]

I have a server using Windows 2000 Advanced. I went
through the wizard to add VPN access and set up the
users. The server is behind a Linksys BEFSR41 Router. I
have used port forwarding to open ports 47, 50, 1723, and
500. I have enabled IPSec, PPTP, and PPPOE pass through
on the router. The router supports protocols 47 and 50.

My clients cannot access the server. I believe I have set
up the VPN server correctly, and I think I have the
permissions set up correctly. My clients get error number
721 or 800. My clients are using Windows XP Pro and
connect using cable or ADSL. None are using dial up
connections at this point. Although I can't predict that
none will ever use dial up.

Can anyone direct me to a book or site that will provide
with the information I need? I need step by step
instructions for both the server and the clients.

I am at a loss. I am sure it is the router that is my
problem, I still can't get a connection for my clients. I
have tried everything I can think of.

Please don't direct me to any consultant's pay sites or
sites with rudimentary solutions. I tried most easy
solutions.

Can someone help me set this up correctly?

Thanks.

statically. I also need to know how to set up the
clients. Do I use the name of my server or the static IP
I assigned?

Should I be able to access the VPN from the computer I
share the ADSL with?

Thanks.

1. Use the remote access server option in the wizard, not the VPN server
option. The VPN server option sets packet filters to block all non-VPN
traffic, and should only be used for a VPN ONLY server.

2. How is your server connected to the Internet? Does it have just one NIC
and connect through the Linksys?

3. Before you try connecting from the Internet, check the server config by
making a VPN connection from a LAN client. VPN will work over any IP
connection. This allows local debugging of server setup.

4. When a LAN connection works, try the VPN connection from the Internet. If
you have forwarded PPTP (tcp port 1723) and allowed GRE on your router, you
should be able to make a VPN connection to the public IP address of your
router. The initial connection must be to a public interface accessible from
the Internet. The PPTP packets will be forwarded through the LAN, and the
VPN connection established with your RRAS server (as it was on the LAN).

5. The encrypted VPN data travels as the payload of IP packets with GRE
headers and public IP addresses. They will be forwarded through the LAN and
stripped and decrypted by the RRAS server. In the reverse direction, the
traffic is encrypted and encapsulated by the RRAS server, then forwarded to
the router for delivery across the Internet.

Try getting into the setup of the Linksys go to "Advanced"
and check the box to enbable PPTP

I have done this and every other thing I can think of. I
think I have done all of the easy solutions. I just can't
get the darn VPN to work. Could it be how my clients are
setting up thier connections? I am at a total loss.

I would like to speak to someone who has a similiar setup
and got it to work so I could piggy back on their
knowledge.

Thanks.

Can you make a VPN connection from a LAN client? If not, what error
message do you get on the client?
