Dorm to College

[Guest]

Okay, I need everyone's help with this one... Let me explain the setup and then what I want to do/my problem.

I have a Netgear MR314 802.11b wireless router hooked up to a cable modem. I have four computers (A, B, C, and D) in my house. A, B, C, and D are all Windows XP Professional and all have Remote Desktop enabled. I am able to use RD within the network so that A can access B, C, or D and B can access A, C, or D, etc etc.. The firewall allows Port 3389 to be sent to Computer A.

I will be attending college this fall and, since my parents are not the most computer-savvy people in the world, I wish to access Computer A so that I can fix problems, show them how to do something, etc. I also fix the neighbors/friends/other family computers, and those people have agreed with me to set up Remote Desktop so that I can fix their problems from college.

The problem is that I can't seem to get RD to work over the Internet. For instance, I can access Computer A by typing "Computer A" in the Remote Desktop computer name/IP address space (I can also type in the local IP address on the network, 192.168.0.11) to do this as well); however, I can not access Computer A (this is the same one the router is programmed to forward port 3389 to) by typing in the IP address of my cable modem (the public IP assigned to me).

Correct me if I'm wrong, but I should be able to type my public IP address in the box in RD and it should directly connect to the computer that the router has forwarded the port to (in this case, Computer A). However, I simply can not remote desktop over the internet.

In the "domain" box should I type in the name of the computer I'm connecting to? Does RD not function correctly when the client making the request is from the same public IP as the host it's being sent to? Since the port is forwarded and the remote desktop is enabled on every computer, the RD call should work, in theory, but it doesn't.
Please tell me what I'm doing wrong and how to set it up!!!

When you test remote access to "Computer A" using the public IP you must be at a remote location,
ie. at a neighbors house for example. It is not a valid test to call from one of your local PCs, ie
"Computer B" for example, using the public IP of the router, and try to connect to "Computer A".

You should leave the domain field blank your case...

I am not sure that I fully understand, but here is a recap:
- Your Netgear forwards 3389 to Comp A (make sure it is the TCP port that
gets forwarded)
- You can access A,B,C, using RDP in any combination by using either IP or
name
The question is are you trying to access Comp A from Comp B by using the ISP
public IP?
If that is what are you trying then your router will most likely not route
internally, for example:
- Comp A IP = 192.168.0.10
- Comp B IP = 192.168.0.11
- Netgear / ISP Cable Modem IP = A.B.C.D
If you are trying to access Comp A from Comp B by typing ISP address A.B.C.D
it may not work especially with netgear, try new firmware maybe you get
lucky.
If you are trying to access Comp A from outside your network, like your
friends PC, then use A.B.C.D. not name.
To check if it is an issue with your ISP make Comp A DMZ for the purpose of
testing if it works then your port forwarding is not setup correctly in the
router.
