Specs: Windows 7
I'm having a problem when trying to administer
a company's servers via RDP. This all worked
fine until about 1 month ago and since I have
not been able to connect. The company have
recently had a new firewall put in place but my
external IP address is listed as trusted. I have
tried ping and tracert and recived the following

Obviously the firewall is the issue since it's the only thing that's changed.

The make/model of the firewall would have been helpful but I suspect we can help you without that info.

Making yourself trusted doesn't seem to have done the trick so I suspect you still have to do a port forward inside the firewall's configuration.

When you try to RDP I expect you're trying to RDP in to a specific computer within the LAN behind the firewall. Right now, even though your PC is listed as "trusted" within the firewall, when the RDP request hits the firewall, it doesn't know what to do with it.

Check in the firewall settings for port forward. When you find it tell it to forward the RDP port (3389) to the internal (LAN) IP of the computer you need to connect to.

Then the firewall will know what to do with the RDP request when it comes in and you should be able to connect correctly again.

I would suggest to use VPN to connect to your company. When VPN connection is established and your computer get's a privat ip address of the companies LAN, you can access every computer through RDP, without the need of port forwarding to each computer you'd like to administer.
And, it's more secure.

The original poster should always write the last response !!!
Let us know, if the problem is solved !!!
