VPN Client, behind a ISA Microsoft proxy which ports need to be open.

[ddisalvo]

What needs to be done on a Microsoft Proxy to let the VPN client 3.5 through?

Someone else may be able to throw more light on this, but the last I heard there was an "issue" with ISA that prevented the Cisco VPN client from operating properly through the ISA server regardless of UDP/TCP tunneling or any other settings.

I'm starting to believe that more and more since I followed a Microsoft Knowledge Base article 812076 step by step and no luck.

Do you know of any official documentation stating this? Or does anyone out there no a way around this problem?

Thanks,
