|موضوع: Setup a Windows XP VPN 6/10/2008, 1:11 pm|| |
In just a few simple steps you can setup a secure VPN using software builtin to XP to create a safe tunnel between a laptop and your home pc.
Create a user account and password for the VPN
Setup the VPN Server on your home PC
Setup XP VPN Client on your laptop ( or Windows 98 )
Test the connection from home first
Create a user account for the VPN
If on your home pc you don't have seperate user accounts for each member of your family, or if you don't use passwords on your user accounts, you will need to setup a new account - with a secure password, that you use for the login credentials of the VPN. If you already use passwords on your user accounts at home, then as long as the password is reasonably secure, you can skip creating a new account, and move straight onto setting up the VPN server. To Create a new user goto Start -> Control Panel and click on User Accounts. Now click on Create a new account. You need to pick a name for the new account, I normally choose something obvious like VPNUSER Click next to continue. You now need to decide whether this is an admin or guest account. Given we are only using it for a VPN it only needs to be a limited account. Next click on the Create Account button to actually create the account. You will now be back at the User Accounts page. Now we need to set a password for the new account, so doubleclick on the newly created account in the "pick an account to change" section. Click on Create a password ...and enter a password in both password boxes. You can leave the hint box empty if you are good at remembering passwords. Click on the Create Password button. Congratulations, you've now completed the first step in creating a VPN connection, you've setup a username and password to use to authenticate the VPN connection.

Setting up the VPN server
To setup the server end of the VPN connection, we need to create a new connection, and then check the firewall/router settings. Firstly bring up the control panel by clicking on Start -> Control Panel. If the control panel is in Classic View as shown below, then click in Category View to see the simplified panel.
From the Category View click on </I>Network and Internet Connections</I>Now click on Network Connections from the or pick a control panel icon sectionSelect the Create a new connection from the menu on the left of the screenYou should now see the New Connection Wizard click next to start.Select Set up an advanced connection and click next to continue.Select Accept incoming connections and click next to continue.Leave the boxes unticked on this next screen and just click next to continue.Select Allow virtual private connections and click next to continue.You now need to pick which users are going to be allowed to vpn in. If you created a user earlier, then ensure that just that user is ticked, else pick which user you want to use - remember they need a secure password. Then click next to continue.You can just click next to continue on this Networking Software screen, as you should already have everything you need installed, as you must already have either a modem or network card in the pc.Congratulations, you've now completed the second step in creating a VPN connection. Click Finish to close the wizard.You should now see your new incoming connection in the Network Connections Window.The last step is to ensure that all incoming connections use encryption (otherwise all this was for nothing !), so right click on the Incoming connections icon and select properties, then go to the second tab Users and tick the Require all users to secure their passwords and data checkbox, and then click the OK button to close the dialog

Testing the VPN Setup
Now the client and server are setup, we just need to make a few final checks before testing the setup.
If you use a modem on your home pc to share your internet connection, then you should be ready to start testing, as setting up the XP VPN Server will automatically update XP's built-in firewall with the rules necessary to allow incoming VPN connections, also you must already have Internet Connection Sharing setup in order to share your internet access.
If you use a router to access the internet and share your connection between computers then you will need to poke a hole in its firewall to the VPN connection through. You will probably need to look at the manual for your router to see how this is done, but you will most likely need to setup port-forwarding on the router to forward TCP connections on port 1723 to your home computer. This should be enough for most home routers.
Instead of going to the nearest internet cafe to test your vpn connection, the easiest way is to test it from home. Use the modem in your laptop to dial your dialup ISP ( most ISPs offer a dialup service with no monthly fees ) and then dial your VPN connection to connect through to your home PC.
Once successfully connected, you should see the new incoming connection shown in the Network Connections control panel of your home pc
If it has connected ok, you should now be able to surf all your regular sites and check your email from your laptop, all through this secure connection.
Once you are happy that it is working over a dialup link, you need to go to your regular wireless internet cafe and test the connection from there. It should obviously be much faster than over a dialup, while keeping all of your web and email traffic safe from prying eyes.
