Such a rule already exists.

I recreated the rule after rerunning the CEICW. Problem persists.

No. It's a Netgear FVM318. By the way, this all works fine under ISA2000.

I have the same problem connecting from the server. I can connect to the VPN
server from clients not behind ISA 2004.

Yes.

> 4. Please help to gather the ISA Info:

I will not be able to get to this until next week.

> 10) Temporarily disable the Firewall service. To do that, please click
