OK, I re-installed XP on my pc and resetted my MN-620 router, I have port 3389 on, and I still can't connect from work to home, I've done everything and I don't know whats wrong, another guy has the same ISP and he can remote desktop to his home pc without any problems, why won't my MN-620 work?
 
Well, it continues to sound like a problem with the MN-620...What exactly? I have no idea...

Is there another way of setting up Port forwarding instead of the setting on the router, Do I have to add the ports on the Nic itself aswell as the router? What about in the registry do I have to set up something there? How can I tell if the ports are listening? I do a netstat and it only shows ports 1678 1679 1680 et. not 3389 how do check to see if that's listening

No... All port forwarding in the case of you using the router is done on the router...

You can do a...

netstat -a

....from the command line on the PC your trying to reach, ie. the Remote Desktop host, and should
have a line that looks like this...

TCP <YourPCName>:3389 <YourPCName>:3389 LISTENING

Example from my XP Pro box...

TCP ashtabula:3389 ashtabula:3389 LISTENING

But, with that said if you can connect over the local LAN to that PC (which you said you could do in
an earlier post) its not a problem with the Remote Desktop host PC and points right back to the
router.

I would try a different router on your home LAN or try your router on a friends LAN to see if the
problem follows the router.

Another test might be to connect one of your PCs directly to your broadband modem and see if you can
connect via Remote Desktop from work or another remote location. Run the Internet Connection
Firewall (ICF) while doing that. You can configure the ICF to open just TCP Port 3389 to that PC.

Make sure you disable the ICF after you return your network to a normal configuration again...

Ok, I do a Netstat -a and all my ports are listed but....this is what I get
TCP <MyPCName>:3389 <MyPCName>:0 LISTENIN
TCP <MyPCName>:1723 <MyPCName>:0 LISTENIN
TCP <MyPCName>:1724 <MyPCName>:0 LISTENIN
and then some are like this..
TCP <MyPCName>:1500 *:* LISTENIN
TCP <MyPCName>:1501 *:* LISTENIN

How can I change these examples to point to the right ports? I've never seen this before ever, what do I have to do

Ooppsss... My mistake... Your correct and my example should be...

TCP ashtabula:3389 ashtabula:0 LISTENING

Sorry about the confusion...

Again, this all points to the router as the root cause of your problem... I recommend you post to
the...

your MN-620 device.

Why does RDM use port 1723 I've seen a few topics on this? Do I have to activate this port to?

Remote Desktop, the Remote Desktop Protocol (RDP), only uses TCP Port 3389.

Some folks may use Remote Desktop through a PPTP VPN tunnel, or an IPSec/L2TP tunnel, for...

a. Added security...(although the RDP data stream is natively encrypted)...
b. An easy method to access more than one PC for Remote Desktop without punching a bunch of holes in
their firewall for "port forwarding" or "port redirection".

In addition to TCP Port 1723 (PPTP VPN) you would also need the router to pass GRE Protocol 47
traffic. Some routers call that "PPTP Pass Through" or "VPN Pass Through" or, like the XP ICF,
automatically enable that if TCP Port 1723 is opened.

So, in your case the only port that needs to be forwarded/opened in your router is TCP Port 3389.

If you were trying to use the web based method of Remote Desktop access then you would also need...

a. IIS installed and running on the target PC or another PC on your network *AND* have IIS Remote
Desktop access configured.
b. Both TCP Port 80 (IIS) and TCP Port 3389 (RDP) forwarded/opened in the router.
c. Your ISP does *NOT* block TCP Port 80 because its against the User Agreement to run Web Servers
on home networks.

With all that said, if you can not make the basic Remote Desktop connection work through your router
then the web based method also will not work. Also, you may have problems with getting a VPN tunnel
to work also.

I hate this...I plugged my computer directly to my pc, turned on the ports and I still can't connect to my pc, what the heck is going on? What am I doing wrong? I followed the sets excatly and it still doesn't work! I've turned on the ports in ICF but still nothing. Tracert works ok so I don't know, tried telnet that doesn't work either
