Unable to use RDC through VPN wile the Firewall Client ... - 20.Oct.2006 7:26:09 PM

With the Firewall Client enabled, I am able to make a PPTP VPN connection to another Windows domain but I cannot get Remote Desktop Connection to work. If I disable the Firewall Client on my machine then RDC works. I am able to use RDC with a Terminal Server host with the Firewall Client enabled and I have successfully used an SSL VPN connection with the Firewall Client enabled, so it appears to be specific to me trying to use Remote Desktop from my machine through a VPN connection to another network while the Firewall Client on my machine is enabled.

I am running ISA Server 2004 on SBS 2003 with every update that I know of installed. The client machine that I use for RDP is running Win XP.

I suspect that there is a problem with my Firewall Policy or Proxy settings but the Firewall Policy that applies when the Firewall Client is enabled is the SBS pre-configured 'SBS Internet Access Rule' which allows all protocols from the internal network for all users in the 'SBS Internet Users' group.

Any suggestions?

Patrick Headley.

Hi Patrick,

check out http://www.isaserver.org/articles/IPSec_Passthrough.html, particular section '4. Configuring ISA Clients'.

Is that IP you are connecting to listed in your "Interrnal Networks" section? (is it included in one of those ranges)

I had experimented with putting the IP addresses on the internal network but I was concerned about giving someone on that network access to my system while I was logged in or for some virus or malware to be transfered into my network due to the relaxed firewall rules.

I'll reread the KB artical.

Patrick.
