I have a PIX 506E and I have it attached to a cable modem and had it configured to use an IAS server for authentication as documented. It was working fine until I switched my IP Addresses from my provider and now I can get out to the Internet and can connect into my exchange and web servers but my VPN tunnel does not work.
I get a prompt for authentication and it sits and spins saying securring communications but it never does.
I get the following error when on my client
17:42:32.046 02/10/05 Sev=Warning/3 IKE/0xA300004B
Received a NOTIFY message with an invalid protocol id (0)
I can e-mail my config to anyone that might be able to help.
