Remote Desktop Client access issues

By VolleyGuy4 ·
My Windows XP computer is not accessible from an XP computer outside the LAN using the Remote Desktop Client (RDC). It was working when I set it up the first time. Nothing changed as far as I can tell.

It is accessible from a computer on the LAN accessing it on the same subnet using private IP addresses. I can also access it from a computer on the LAN and typing our outside static IP address and the RDC port#. We have a DSL router with a built-in packet filtering firewall but we have enabled port forwarding.

The question is why does it work for a local computer going out to the Internet and back but not from a remote system?

Thanks in advance, Guy...

When you are trying to remote into your office to your computer it is going to hit your router and then your server since all internet traffic comes from those. Unless you have your router forward that port to your machine, you arent going to get that far.

I do have the router forwarding that port to the specific PC. That's what I meant when I said "We have a DSL router with a built-in packet filtering firewall but we have enabled port forwarding." Sorry I didn't make it clearer.

gotta be the firewall in the router then. which model router? can you turn it all the way off for a test. (i know you have the port forwarded and i am suggesting this anyway)

We decided to not spend anymore time on this project. I was going to call Efficient Networks to find out the best way to turn off the firewall and setup a DMZ. Boss didn't want to spend the money or time. Thanks for your input.

well, there are some stories out and about on consumer level routers and remote desktop problems. One from SBC the Cayman DSL router/ modem seems to have more problems that others. The Linksys BEF series routers also seems to not like the RPC call for remote desktop.

If you can configure a DMZ port on the router try that and see if you still have problems getting in on Remote desktop [assuming Remote desktop/remote assistance is turn on and properly configured]. If you still have problems getting in on a DMZ port then its the router and time to get something different.

The DSL router is a Speedstream 5861-005 made by Efficient Networks and the DSL service is provided by SBC. I will try to turn off the firewall completely to see if that helps. If it does, I will try to setup a DMZ and let you know. Thanks for your help, Guy...
