Client blocking RDP and VNC - 18.Oct.2007 9:49:53 PM

Hi,

I've got a weird problem I can't figure out. When enabled, the ISA firewall client blocks outbound RDP and VNC traffic. If I disable the client, the connections work fine. I have no rules configured in the ISA server that explains this behavior (but I do have a rule specified to allow ALL outbound traffic).

I've got ISA 2006 and the client is 4.0.3442.

Any ideas?

Surely someone has an idea? I still haven't got it figured out.

are you attempting to access a VNC or RDP host on your internal or external network?

I have the same problem. When client is SecureNAT, I can VNC and RDP out with no problem. When the client is a FW client or WebProxy client, I cannot VNC or RDP.
I have created a custom protocol and an access rule allowing a specific group of people to use VNC. But unless I allow "all users" to have "all outbound traffic"... I have no luck.....

Please help.......
