Hi all-
I was wondering how I could accomplish a standard port forwarding or port redirection for a standard service like RDP.
Scenario:
ISA Server 2006 shall redirect incoming requests for port 3380 to an internal IP address with port number 3389.
I already tried this by setting up a firewall rule and changing the ports but neither could I establish a connection successfully nor was a log entry made.
Any ideas, whitepapers, or help?
Cheers,
Holger

Hi Holger,
that's easily accomplished in ISA 2006. Start with a standard RDP Server server publishing rule. On the Traffic tab there is button Ports. There you can change the TCP ports used.

Hi Holger,
is the published host configured as a SecureNAT client only? It should.
Also, what is the ISA live logging telling you?

Hi Stefaan,
yes that's right. The host (Win 2003) is configured to be just a "normal" client that accesses external resources over the ISA Server 2006.
And the live log doesn't even show the attemted connection...
If I replace the ISA with an "ordinary" packet filter port redirection works fine.
Cheers,
Holger

Hi Holger,

There should be an entry, good or bad!
What's the result of the command fwengmon /C | find ":3380"?
Any chance to take a NetMon trace on the ISA external interface?
HTH,
Stefaan

Hi Holger,
just open a command windows and run that command.
If it's not in the path, it might be in the directory "C:\Program Files\Microsoft ISA Server>". If you couldn't find it on the ISA box, download it from Firewall Kernel Mode Tool for ISA Server 2006.
HTH,
Stefaan

but the result was that the connection attempt has always timed out. Anything else that I should do?
