Hello all, It is my understanding that Cisco co-wrote the IPSec code for Windows 2000. If you want to check for yourself go to the Windows help file for IPSec. It is also possible to use the built-in IPSec client in Windows 2000 and connect it with a Cisco PIX firewall or a router running IOS. The problem everyone having wasn't due to the IPSec implementation itself. The problem was due to the fact that MS decided to support only L2TP in it's IPSec implementation. Most IPSec VPN softwares only use ESP and some support both ESP and L2TP. It took awhile for Cisco to release a version of the PIX and IOS firewalls that supported L2TP. As of version 6.0 of PIX and I think 12.1 of IOS you can make a W2K to IOS/PIX connection without the need for other software clients. The setup process isn't pretty but it does work and I've found it to be fairly reliable. Just make sure you specify that you want to use L2TP in your crypto statements. ESP is used by default. -Steven Griffin
