Help Creating a VPN Tunnel for Remote Desktop Access.....

June 9, 2012 at 16:04:16
Specs: Windows XP Pro SP2
I have the ability to access a network I have at work from home because it is connected to the internet. The router I have is a Netgear DGN2200 and it has the ability to create a VPN but I'm not knowledgeable enough to do this.

I have a computer at work that is connected to this network that I will like to use "Remote Desktop" from Microsoft to connect to it from home using the VPN connection. II will really appreciate if anyone here can help me with this process. One small detail is that the computer at work, I don't have administrator rights. I will need to be able to create a user account to create the VPN, correct

Do you guys know of any other way, perhaps using some sort of third party software?

First and most necessary is, are you allowed to create a VPN or any other connection to the company network?
Is there an administator and did you spoke to him?
He can help you on this problem.

This computer is not connected to the company intranet. This network only encompass the automated machinery PLC's. I'm already using a software called "TeamViewer" to remote into this computer and troubleshoot problems in the equipment. The IT department in our company is not responsible for this network. The person that put this network together, which doesn't work in our facility, is the one who setup the "Administrator Password".

The Netgear DGN2200 provides up to 5 VPN connection (client to site (or gateway as described in the manual)).

So put a Netgear DGN2200 at the side of that computer you'd like to connect to.
Configure the client to gateway VPN as described in the routers manual starting at page 99.
Install the Netgear ProSafe VPN Client onto your computer, do the configuration as described at page 101 of the routers manual.

Thats it.

Btw: What's wrong with TeamViewer?

Being able to use "Remote Desktop" I think is going to provide me with a better experience than using "TeamViewer". I will still use "TeamViewer" for their android App which will allow me to see what's going on at the plant while I'm on the road.

Do you think that I could use perhaps "logMeIn Hamachi" which is free instead of Netgear ProSafe VPN Client.

Ok, TeamViewer reduces the colours, cuts some other details for displaying the screen, depending on the quality and speed of the connection.

VPN tunnel itself needs a portion of speed for itself, for tunneling and encryption.
The rest of the speed can be used by Remote Desktop.

I prefere RealVNC for such things.
The commercial version supports encryption, works fast and reliable.
The display quality also depends on the quality and speed of the connection.
But all in all, you get a much better quality on your screen than with TeamViewer.

Disadvantage of RealVNC:
When the remote computer works on dynamic public ip address, you need services like No-IP or DynDNS, to be able to access the remote computer.

TeamViewer works with central servers, where the TeamViewerQS program transmits the current public ip address to such servers, so that one gets the current ip address of that machine from this servers. So no No-IP or DynDNS is needed.

So you are suggesting that I should stick with "TeamViewer" as its lets painful to use. By the way, the computer I'm trying to access has a static IP address.

Just for my information.
The computer in question uses a public static ip address?

Yes it does Paul and I still can't understand why they opted to use public IP addressing for this network.

Maybe because this computer do not need to communicate with the internal private network.

Anyway, in that case, you can use e.g. RealVNC (commercial) or UltraVNC (which is free and also supports encryption by using a plugin).

For RealVNC, you need to use the commercial version, cause the free version does not provide encrypted connections.

Paul, now that you mention UltraVNC I forgot to mention that this computer has UltraVNC installed in it. I didn't knew that I could use this software to do the VPN connection.

This machine is serving as a server to several clients in production floor, and I think they are using UltraVNC to do this. Any idea how UltraVNC is used to achieve the VPN connection?

It isn't used for VPN connection.

It can establish encrypted secure connections between "server/computer" and "client/computer".
You need to download the plugin for encryption.

Here, you'll find the latest version of UltraVNC to download:

Do I need to install the full version or just the viewer, Paul on the computer I want to use to access the server/computer.

Do I install the plug-in on both computer?

You have to install the full version at the computer, acting as a server and the viewer at the client computer.
The plugin has to be installed on both sides, cause both sides must be able to encrypt the communication.
