Remote Desktop via VPN problem

I have a server running Windows 2000 Terminal Server. The remote desktop works (inside the building) from client computer to the server by filling in the name or the IP address of the server. When I get home, I establish my VPN connection, then remote desktop doesn't work with either name or LAN IP address. I have the ports set up correctly in the router (1723 for VPN) and (3389 for RDT) to the server's IP address. My VPN connects at home using the Static IP Address. The only way to connect to the Server is to enter the same Static IP Address which isn't secure. Server is running Active Directory with DNS and Router is DHCP. My error message at home is "Can not find the computer, try again later".....Please Help, Thank You.

    What do you mean by "The only way to connect to the Server is to enter the same Static IP Address which isn't secure" ?



    Are you saying that

    - this works right now (i.e. internal server has a Internet routable IP address)

    - you have to setup the router to forward ports to the internal ports?

    - Once the VPN Client is connected to the server, then trying to remote desktop into the router remote desktop into the server?

If you opened port 3389 for TCP on your firewall you do not need VPN.
You do need to make sure that port 3389 is forwarded to the private IP of the server on the firewall or it won't know where to direct your connection.

Once you are sure this is set just open RDP, enter the public IP of your firewall and connect. Do not make a VPN connection.

Unless you specified on your firewalll to only allow conections from your home network you home IP has nothing to do with the connection.

Now the point of using VPN is not having to open any of those ports. Ultimately, you do not have to open any ports because VPN, when properly configured will give your computer an address on the server's LAN and allow you to connect using its private IP.

Clearly, this is way more complex that a post at FixYa.com. You should call your firewall vendor for high-level, interactive support and for the unique requirements of your specific firewall.

If this helps in any way please vote for my solution.

Make sure that the Active Directory setting for the User you are using to RDP with (LDAP FQN) has the remote access option turned on.

Also make sure that the PC's you want to access have static IP addresses. Not sure if that was mentioned.

Hi. I want to set up a server and run dumb terminals (thin clients) off of it. Can anyone give me a basic run-down about how I do that?


You would setup Windows Server. Windows Server 2003 and 2008 Small Business Server comes with a license of Terminal Services Server.

You would first need to setup your Windows Server. Install it according to at least minimum requirements.

Make sure you assign this server the correct role. If this is the primary server and if you intend on hosting dns and dhcp on this machine, then please make sure you are assigning this server these roles.

You will need to create user accounts so that you can log into from your thin clients.

Next you need to run the install for Terminal Server.

Next you need to configure each thin client.

Next try to access each thin client via Remote Desktop as well as the server.

This is the basic run down of the process. If you do not know how to setup a server then you will need to ask that question as this is very detailed. Also you will need to be more detailed in your question as to whether this is a linux based network or a windows based network.

Hope this helps. Please don't forget to give me a good rating as well as your vote.

Tip

VPN in Microsoft Server 2003


The full form of VPN is Virtual Private Network. VPN gives extremely secure connections between private networks linked through the Internet. It allows remote computers to act as though they were on the same secure, local network. Allows you to be at home and access your company's computers in the same way as if you were sitting at work.

Almost impossible for someone to tap or interfere with data in the VPN tunnel. If you have VPN client software on a laptop, you can connect to your company from anywhere in the world. VPN goes between a computer and a network (client-to-server), or a LAN and a network using two routers (server-to-server). Each end of the connection is a VPN "endpoint", the connection between them is a "VPN tunnel".

When one end is a client, it means that computer is running VPN client software. You can use a virtual private network (VPN) to connect components to one network by using another network. VPN do this by "tunneling" through the Internet or another public network. With a VPN, connections across the public network can transfer data by using the routing infrastructure of the Internet, but to the user, the data seems to travel over a dedicated private link.

A VPN gives you the benefit of a dial-up connection to a dial-up server, plus the flexibility of an Internet connection. Using an Internet connection you can connect to resources all over the world. If you have a high-speed Internet connection at your computer and at your office, you can communicate with your office at full Internet speed. This is much faster than any dial-up connection that uses an analog modem.

VPNs use authenticated links to make sure that only authorized users can connect to your network, and they use encryption to make sure that others cannot intercept and cannot use data over the Internet. A Tunneling Protocol is a technology that helps make the transfer of information over the Internet more secure from one computer to another.

VPN technology also permits a corporation to connect to its branch offices or to other companies over a public network, such as the Internet, while helping to maintain secure communications. The VPN connection across the Internet logically operates as a dedicated wide area network (WAN) link.

VPN in Windows 2003 Server: You need a high speed Internet connection to configure and run VPN server. Two individual lan card must be present in a single system where you want to configure a VPN Server. The lan cards should ping each other. Also need a User which's Dial in allow access should be enable. Microsoft 2003 server two tunnelling protocols for a secure VPN connection, one is PPTP (Point-to-Point Tunnelling Protocol) which Provides data encryption using Microsoft Point-to-Point Encryption. The other is L2TP (Layer Two Tunnelling Protocol) which Provides data encryption, authentication, and integrity using IPSec.

Steps to create VPN Server in 2003 Server: At first I go to Start and point to Administrative Tools, then click Routing and Remote Access. Then I click the server icon that matches the local server name in the left panel of the console. If the Routing and Remote Access service was previously turn on, you may want to reconfigure the server.

To reconfigure the server Right-click the server object, and then click Disable Routing and Remote Access. Click yes to continue when you are prompted with an informational message. Then Right-click the server icon and then click configure and Enable Routing and Remote Access to start the Routing and Remote Access Server Setup Wizard. After that click Remote access (dial-up or VPN) to turn on remote computers to dial in or connect to this network through the Internet. Then I have Click to select VPN. In the VPN Connection window I click the network interface (Lan) which is connected to the Internet and go the IP Address Assignment window, then I click Automatically because there was present a DHCP server in network. However, if DHCP is not available, you must specify a range of static addresses.

If you use from a specified range of addresses, open the Address Range Assignment dialog box and Type the first IP address in the range of addresses that you want to use in the Start IP address box. Type the last IP address in the range in the End IP address box. Windows calculates the number of addresses automatically. After that I have accept the default setting of No, use Routing and Remote Access to authenticate connection request and finally Click Finish to turn on the Routing and Remote Access service and to configure the server as a Remote Access server.
For the remote access server to forward traffic properly inside your network, you must configure it as a router with either static routes or routing protocols, so that all of the locations in the intranet are reachable from the remote access server. It also need for security purpose.<SPAN style="LINE-HEIGHT: 115%; FONT-FAMILY: 'Verdana','sans-serif

Assuming you can connect via Remote Desktop without any issues...
Printing through Terminal services requires that printing be enabled in the Terminal Services Configuration (Client Settings Tab). It also requires that the printer driver be installed on the Terminal server, not the actual printer (as it shows under the control panel) but just the driver. You can install just the driver by going to File/Server Properties under Printers and Faxes ON THE TERMINAL. Install the printer normally on the client machines.
Note: For a printer to work via Terminal services it needs to have a compatible driver (which I believe is called PCL??) So some consumer printers (the ones that only come with Setup programs, not just driver packages) will not work. The majority of HP Officejets and laserjets are fine, as are Brother lasers.

Remote desktop


Here is a short list of applications that can be used.
1) VNC (Virtual Network Computing) is a remote display system which allows the user to view the desktop of a remote machine anywhere on the internet. It can also be directed through SSH for security.
Basically you install VNC server on the server and install client on your local PC. Setup is extremely easy and server is very stable. On client side, you can set the resolution and connect to IP of VNC server. It can be a bit slow compared to Windows remote desktop and also has the tendency to take more time refreshing over low-bandwidth links. All in all VNC is an amazing piece of free software that gets the job done.
There is RealVNC , TightVNC and UltraVNC. Each has it’s advantages and disadvantages. Most popular one is RealVNC but if you’re upto it, experiment with all three and choose the one that works for you best. By default, communication between client and server is in clear text on port 5900. However, you can easily route all traffic via SSH tunnel. Here is a quick way of setting it up if you have access to command line shell:
ssh -ND 5900 <user>@remote.server.com
When you get prompted, enter your password. Pop open VNC client and connect to ‘localhost’. This’ll route your connection to VNC server on remote machine.
You can download VNC from:
  1. http://www.realvnc.com/download.html
  2. http://www.tightvnc.com/download.html
  3. http://www.uvnc.com/
2) Then there is FreeNX. FreeNX is a system that allows you to access your desktop from another machine over the internet. You can use this to login graphically to your desktop from a remote location. One example of its use would be to have a FreeNX server set up on your home computer, and graphically logging in to the home computer from your work computer, using a FreeNX client. It provides near local speed application responsiveness over high latency, low bandwidth links.
FreeNX can be configured to run via SSH without any tunneling. It binds to your existing SSH install. Instead of guiding you through the installation of FreeNX in this article, you can visit the following URLs that’ll guide you through the installation on Ubuntu:
  1. https://help.ubuntu.com/community/FreeNX
  2. http://ubuntuforums.org/showthread.php?t=97277&highlight=freenx
  3. http://freenx.berlios.de/ (FreeNX homepage)
3) The third free application is 2X Terminal Server for Linux. 2X TerminalServer for Linux is an Open Source project, licensed under the GPL and is free of charge. As far as performance goes, NoMachine’s technology is on par with Windows’ own Remote Desktop Protocol (RDP) suite, better than VNC. Both X2 and FreeNX is based on NoMachine technology.
Here are some quick links if you’re interested in using this software:
  1. Download at http://www.2x.com/terminalserver/download.htm
  2. Forum is at http://www.2x.com/forums
4) The last but not least at all is XDMCP. The X Display Manager Control Protocol uses UDP port 177. Compared to the list above, it’s not as easy to setup for remote desktop but it’s the original way of doing this on Linux. You can get setup instructions and other tips in the following URL:
  1. http://www.tldp.org/HOWTO/XDMCP-HOWTO/intro.html
In conclusion, there are many commercial products that are available as well. But this article is only based on open source products that can be freely used with no strings attached.

Setting up a VPN through watchguard


The key with any VPN solution is to make sure that the configurations on both ends match. I am not very familiar with this particular product, but it looks like you need to have the proper VPN licenses installed first. There are two types of VPN you can do. 1) Site to Site - This is where the are two static boxes that you want to create an encrypted tunnel between 2) Remote User access - This is where mobile users connect to a central site over an encrypted tunnel from their home or on the road. Next, take a looks at the User Guide PDF here: https://www.watchguard.com/help/documentation/soho6.asp Chapter 10 tells how to configure the VPN on the Firebox side. You would just duplicate your settings if your doing option #1. Chapter 11 tells how to configure the VPN on the client side. This section would tell you how to configure the client software for option #2. Hope this helps.
