Setting Up VPN on Small LAN?

Hello - I need to setup a VPN between two PC's attached to separate, small
LANs. Both run XP Pro. The client seems easy to do, just follow the Windows
Network Wizard, where do I start to setup the VPN Server? Here's a
description of routers:
* Box A: Static IP, Linksys Broadband Router (RPT31P2)
* Box B: Dynamic IP, D-Link (DI-624)
Is it possible to run a VPN with this setup? If so, where do I start to
setup VPN server.

Thanks, -Bob

You do it the same way. You just set it up to be a "server" not a
"client". You set it up to host an incoming connection.

That is the easy bit. You can check that it works by setting up a client
on the same LAN and connecting from there using the "server's" LAN IP. The
tricky bit will be getting it to work through the Internet. Here are a few
things to consider.

1. The connection through the Internet must be made to a public IP. If
you are connecting to the Linksys with a static IP, this will be OK. If you
are connecting to the D-Link you will need some way of keeping track of its
dynamic IP (like dyndns).

2. You will need to work out how to extend the VPN connection from the
router/firewall device to the VPN host on the private LAN. This will involve
configuring your router device to forward tcp port 1723.

3. The connection will still fail if anything in the path blocks GRE
(Generic Routing Protocol). GRE is IP protocol 47. Do not confuse this with
port 47 (as many people do).

Bill -- When I look at the properties of the VPN Client connection icon (in
Network Connections) I can't find a setting that distinquishes it as
client/server? When I use the "Create a new connection" icon all options
seem to point to 'establishing a connection with a host' and not with "being
the host"?

I meant that you use the same wizard. In the New Connection wizard,
select "set up an advanced connection" option then "allow an incoming
connection".
