"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Checkout openvpn, it is in my point of view much better than the builtin windoze vpn's.
You could try the following:

Install PPTP VPN Server

Download and install webmin ->

logon to webmin usaly http://localhost:10000

Networking -> PPTP VPN Server
Under PPTP Server Options set ip address and ip scope to dish out.
Under PPTP Accounts - setup a user name and password.
Start the server

Could you explain the process of setting up a VPN? Totally, I plan to have 6 machines for my home family, 1 for Red Hat Enterprise Linux 4 AS (Proxy server, Firewall, VPN) that have 2 NICs (one connect to LAN and another one connect to DSL modem), 1 for Windows server 2003 (file server, email server), and another 4 for Windows XP (client machine) which connect together via hub. I have cable internet connection (DSL) with a public IP address.

 I'm looking an explanation of the configurations I would need to make to get this VPN work under the Linux system which mentioned above.

Openvpn has example configs ready for use, they explain that much better than I can...
