Allow RDP through ISA using Firewall Client
Posted on 2010-04-09
I have the following problem.
We've recently installed a Forefront TMG server.
Because of a shared network infrastructure, it's not possible to set this TMG as the gateway (of last resort). We need to be able to access an RDP server on the Internet.
I've installed the firewall client on my machine. As I understand, this should cause all winsock traffic that's destined to internal to be handled by the TMG server.
I've created a rule, allowing RDP to the specific servers for all users.
However, when I try to set up and RDP session, I don't see any 3389 traffic in the TMG logs.
Do I need to configure some application settings for the firewall client? If so, what would they be? Is there anything I'm missing here? Please help! All links I've found so far suggest that it works when I'm a secure NAT client, but that's not an option in our case.
Internal <> External network rule is NAT. Changing it to routing is probably not an option either.
