L2TP Tunneling in Windows Server 2003
Well, I'm looking for a method of replacing a Cisco VPN implementation with the built-in Windows Server 2003 Routing and Remote Access service, which provides a secure VPN tunnel end-point. As far as I know, PPTP tunnels are insecure and generally not recommended, so I'm looking for information on how to implement the L2T protocol. From my research so far, I've learned that you must use certificate authentication and encryption; the problem with this, is that I haven't had a lot of experience using digital certificates in Windows (or any o/s for that matter). Once I get some additional information about this, I'll write up a small guide for other system administrators out there that need to get a secure, and more easily managable VPN solution in place. A lot of you out there may ask why I'd like to replace a Cisco PIX VPN solution with a Windows RRAS solution. Well, the primary reason is that Windows is plenty secure when configured properly, and because using Windows authentication for VPN purges the need to manage two separate user databases.
