This guide describes the configuration of a PPTP connection on Windows XP using the Operating System's built in client.
It is recommended to use OpenVPN to connect to our service.
OpenVPN surpasses firewalls and routers easier and is more secure than PPTP.
PPTP is considered broken and should really only be used on platforms where OpenVPN is not available.
Instead of setting up PPTP, please follow the corresponding OpenVPN guide.
To configure a new network connection on Windows XP, open the Start menu, move on to Settings and click Control Panel.
From within the Control Panel, choose Network and Internet Connections.
After the connection wizard came up, click Next to select the connection type.
A so-called Connection to the network at my workplace is needed, since this implies the creation of a VPN connection. Click Next.
Choose Virtual Private Network connection. The already active Internet connection is used to establish a new one to IPredator. Click Next.
The Company Name can be set to anything meaningful to you, we suggest using IPredator, of course. Click Next.
The Host name you are connecting to is pptp.ipredator.se.
Have a shortcut to the newly configured connection being created on your desktop.
After clicking Finish, you are done with the basic configuration.
You are now presented with a dialog window wanting you to enter your user credentials and to connect to IPredator.
Do not try to connect yet.
To reduce information leaks, you should consider tweaking this connection as described in the next section.
File and printer sharing should generally be disabled on any VPN connection.
By disabling these protocols you prevent your machine from inadvertently leaking information to the Internet.
If you kept the dialog window Connect IPredator open, just click Properties for now.
In case you did create a connection shortcut on the desktop, you can now right click on it and choose Properties
(otherwise it is reachable via Start menu/Settings/Control Panel/Network and Internet Connections).
Either way, a dialog box detailing the network connection's setup will be brought up.
In the General tab, verify that pptp.ipredator.se is used as the host name. Click the Options tab.
Make sure that the Windows login domain is not included.
The Redial attempts should be set to a very high number.
Check Redial if line is dropped to have your machine always trying to reestablished failed connections.
Switch to the Security tab.
Change the Security options to Advanced and click Settings.. to edit these.
Data encryption should be set to Maximum strength encryption (disconnect if server declines).
Further, connections to IPredator are only allowed to use Microsoft CHAP Version 2 (MS-CHAP v2) for authentication.
Click OK to close the Advanced Security Settings and switch to the Networking tab.
Uncheck File and Printer Sharing for Microsoft Networks as well as Client for Microsoft Networks from the list of used items.
The Type of VPN needs to be set to PPTP VPN. Click Settings.
Inside the PPP Settings, it is important to have LCP extensions enabled and to have Software compression disabled.
Close with OK and go on to the Advanced tab.
The most important settings here are those for the Windows Firewall. Get there.
The firewall should be turned on, but allow exceptions. Get to the Exceptions tab.
Uncheck all currently available exceptions.
You might want to open the firewall later for certain programs that need to have communication directly with your machine.
Change to the Advanced tab.
Make sure that the VPN connection is checked, so the firewall is active for it. Close this dialog window by clicking OK.
