We are running Server 2008R2, I installed Remote Desktop Gateway and configured it. It works fine inside the LAN - all machines can be accessed by the Gateway website thru local RDP access.
I exposed the RDG thru ports 80, 443 and 3389 - I can get to the website from the WAN, and the (non-self-signed, real) certificate works - no cert error.
When I access the website from the WAN, login, and go to "Remote Desktop" in the website and enter the name of a server to access (say, "server01 or "server1.domain.local") I get the response "Your computer can't connect to the remote computer because the RDG server is temporarily available" - before I started getting this message, I was getting "Unable to find computer - it might not be part of the domain, etc." - I read that the DefaultTSGateway setting in the IIS website settings in RDWEB\Pages\en-US might need a real value, so I put in the local FQDN of the server with the RDG, and now I get the first error message. No joy.
I also setup a GP just for RDG and enabled the three settings for RDG there and put values in them - also no joy.
I'd really appreciate some guidance - everything looks good, it works internally just fine, but I can't RDP into our servers, I can only get to the website.
Any ideas?
