Forwarding ports for Remote Desktop Connection for 3 or more PC’s

I have 3 PC’s that I want to remote Desktop to, when I am not home.
How do I set up port forwarding for each PC to have a different Port to use for connecting too? All PC’s are Vista and one Server 2003 which I am not worried about the port on it, I can use the default port there.
========================================
I know I can change the Ports that RDP uses on each PC in the Registry under "¦
1 . Start Registry Editor.
2 . Locate and then click the following registry sub key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber
3 . On the Edit menu, click Modify, and then click Decimal.
4 . Type the new port number, and then click OK.
5 . Quit Registry Editor.

But, What I want to know is, what is EH-Tcp with the port number 3390 in my registry?
Do I need to change this port also on all my PC’s I intend to connect to, in the Registry?

After I get this straightened out, I need to forward my ports I set for each RDP-Tcp on my router to the Static IP address I set for each PC.

Below is a link to my web site with the question that i put into web form and with pics. You may also use it as you wish, if you want to save it and touch it up for your own or forum use.

This one is a little better.

Lets say for example you have 2 PC's you need to get to from the internet to keep it simple.

PC #1 leave at default settings.
Forward port #3389 in the router to PC #1 local IP address.

You would connect from the outside with remote desktop by (internet IP or qualified domain name) with no modifications.


PC #2.
Change the RDP listening port to 3390 per the above article.
Forward 3390 in the router to PC #2 local IP address.

From the internet connect using RDP with your (internet IP or qualified domain name) like this: XX.X.XXX.XXX:3390 or: http://www.yourdomainname.com:3390

 

Well I just opened your link in IE instead of Firefox and now it makes a little more sense.

I have a much easier solution for you.

No ports to fool with, no router settings, no IP adresses.
It's just a win win as far as I can tell.

 

Remember that Port Forwarding is only needed to get thu a router from the outside (WAN/Internet).

It is not needed at all from station to station on/inside a LAN!

Keep in mind that if these computers you wish to connect to are on a network with a Server then you only need to port forward to the server.

Once connected to the server you no longer need port forwarding as you can run RDP from the server and connect to any PC on the LAN.

Or even if you have no server but can connect to 1 PC on the LAN then you can contect to all on the LAN by RDP again from that one to any other internal LAN computer.

I use this scenario for system Admin and support. But it would not be very good to set up remote users to run applications on all day long. For that you need a terminal server.

Get a hardware firewall with VPN and connect to it via the VPN. Your laptop them becomes part of the local network and you can access other PCs the same way as you would from the PC on your desk at work. RDP works very well over VPN.

You can use the firewall to control who and what is accessible via the VPN.

That's the system I use and it works a treat. I use a Netasq firewall, but similar units from the likes of SonicWall, Cisco, and Watchguard would work just as well.

However, I also use Netgear SSL VPN unit. It's a little quirky, but has RDP support built in. Its best feature is that it uses SSL VPN so isn't blocked by 3rd party firewall (a problem in hotels that a lot of our guys use). It's also very cheap. Its a very flexible and affordable solution, but I'd put it behind a hardware firewall!

 

Thanks everyone, but I really need to know what the above entry is for, and do I need to mess with it. If that port is the listening port for RDP or If it has anything to with RDP at all.

I also have accounts for logmein dot com. Which i can use.
I am in college and taking Administrative networking and want to learn more about RDP and the ports.

I want my PC's set to be able to connect to each one individually. Incase my home server is not up for some reason. I know that I can use the server to RDP each one after i connect to the network.

I have TSWeb that i use and I made a custom html page for and the default. I will have to adjust some or the settings of course depending on were i put these files, either on my web page server or my home server.
And of course if you find these files useful and want to use them you are more than welcome too. just let me know so i can get them to you.

My TSWeb custom pages. I will have these passworded when I get it set up the way i want. Just for safety reasons.

Reggie, I have a Linksys Router WRT54G Wirless with DD-WRT Firmware flashed on it and it has VPN, I may get into that later of course. And I think you may be able to help me on this when i get ready, or you can post and explain how to set it up in the linksys with DD-WRT Firmware if you want, would be useful to be a little aquanted with it for sure.

Thanks: Jake

 

I think the EH-Tcp port 3390 is for RDP ver 6 (Vista)

 

So, Scott do you think that is the port i should be changing, and the other RDP port in the Registry may be for older versions in Windows XP, or did XP also up date to a newer Version also (V6) I just cannot seem to get a proper answer in most places. I guess due to the fact that it is new.

I have XP installed on virtual Machine so I will check it to see if EH-Tcp port 3390 is in the Registry.

The only one in Windows XP with Service Pack 3 installed is RDP-Tcp port 3389. So the EH-Tcp must be for Vista using port 3390!!

 

That's the way I understood it.

 

I think I have it all working just fine now!

I have 3 PC’s that I want to remote Desktop to, when I am not home.
Question: How do I set up port forwarding for each PC to have a different Port to use for connecting too?
Answer: You need to change the ports that Remote desktop use’s to connect.
========================================
Warning: Backup your Registry just in case something goes wrong, if you are not sure what to do, don't do it.
You can change the Ports that RDP uses on each PC in the Registry under "¦
1 . To Start Registry Editor. Click Start > run> then in the box type "regedit" without the quotes. Hit enter key.
2 . Locate and then click the following registry sub key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber
3 . On the Edit menu, click Modify, and then click Decimal.
4 . Type the new port number, and then click OK.
5 . Quit Registry Editor.
Change the port number to what you want to use, as long as it is not already being used.

RDP-Tcp (3389 is standard port for XP)
Windows XP does not have the "EH-Tcp" entry only RDP-Tcp.

EH-Tcp (3390 is standard port for Vista)
I changed them both RDP-Tcp & EH-Tcp to the same as what I wanted in Vista.

But, What I want to know is, what is EH-Tcp with the port number 3390? Answer: This is for Vista.
You need to change this port also on all PC’s you intend to connect to.

After you get these ports changed, you need to forward these ports on your Router to your local static IP of the PC you want to connect to.

This works!
Use the ports you set in the Registry under EH-Tcp (Vista) or RDP-Tcp (XP) in port forwarding.

Below is a link to the page I made with step by step photos and text to show you how i made it work. I had someone connect externally to make sure it all works.

Thank you all for all your help.

Here is the link to the TSWeb custom I made with instructions and original files.

You can use software VPN like NeoRouter www.neorouter.com. It's much easier to use. You can then use either Windows remote desktop or VNC to access your computer and you can even access your shared folders. It actually creates a virtual LAN over the Internet for you.
