Vista and VPN (Cisco Pix)

Hey Peter,

I was able to get mine working finally. The problem appears to lie in the
authentication methods used. I have several configurations that work, but
you need to provide more information to isolate your problem. Here are two
scenario's that I have encountered and found solutions for.

1. Using the Cisco Client (IPSec)
- Try upgrading to the latest Cisco VPN Client for Vista.

2. Using the Windows Client (PPTP)
- When used with Cisco Devices, the PIX products typically support PAP,
CHAP and MSCHAP v1. Vista uses MSCHAP v2 by default. You can go to the
properties of the connection and force it to use PAP and that seems to work.
(It's almost completely insecure, but at least it works. There appears to
be something wrong with CHAP and Vista has no support for MSCHAP v1. Try
and use PAP and see if it works. The password will be sent in clear text,
which is unfortunate, but at least it will work...
