VNC, or Virtual Network Computing, is a protocol that allows a user to control their computer from afar using a VNC client. VNC takes a bit of time and effort to set up, but when done correctly this setup can provide an easy, efficient, and secure way to access your home or work desktop while on the go.
This demonstration is going to use RealVNC Free Edition. There are a number of other VNC server products available, such as TightVNC and UltraVNC. However, the setup of these products will be very similar to the setup of RealVNC.
Screens 4 is also available for iPad for just $19.99. Being able to log into your Mac remotely can be very handy. Just remember that if you can log into your computer remotely, so can someone else. Every door you leave open into your computer could potentially be used by someone else. Best RDP/VNC Remote Desktop Apps 1. Screens – Remote Desktop, VNC, Screen Sharing ( iPhone + iPad ):-If you want to work comfortably anywhere, anytime, you can use Screens-Remote Desktop, VNC app on your iPhone and iPad that lets you connect back to your Mac or PC. This RDP/VNC remote app has lots of powerful and useful features.
- The first step in configuring RealVNC would be to download the program from the official RealVNC website.
- Once you have downloaded and executed the setup file, you will want to accept the default options, ensuring that you are doing a “full” installation with the server component selected.
- You will also want to ensure that RealVNC is configured in “service mode”. This will essentially allow the program to start with Windows, and to become more integrated into the system. Again, this is important because you will want to ensure that your remote desktop program is always running, and that you always have access to your computer.
- Once installation has finished, you will be presented with the options dialog. The most important thing you will need to change will be the security. Select the “VNC password authentication” option, and click the “Configure” button to enter your password.
- Apply the security settings, and click the finish button to close the installation dialog.
Once you have RealVNC configured, you will need to make this accessible from outside of your network. The first thing you want to do is ensure that your local IP (e.g. 192.168.1.5, 10.0.0.5, etc.) is set to never change. In Windows, this is a relatively simple configuration.
- In Windows XP, use Control Panel > Network Connections, and right click on your connection (usually “Local Area Connection”) and select “Properties”
- In Windows Vista and 7, you will need to open the “Network and Sharing Center” (available by default in your system tray), and select your current connection.
- Once you have accessed the properties for your network connection, select “Properties”, and select the TCP/IP protocol, and select its properties. This will leave you with a dialog to configure your local IP address.
- Your IP address should be in the same range as your routers. For example, if your router’s IP address was 192.168.1.1, an acceptable IP address for your computer would be 192.168.1.75. It is good practice to ensure that the last part of the IP is far enough away from the other IP’s on your network, as not to have any IP conflicts down the road.
- Once you have entered your desired IP, your subnet mask will automatically be calculated, and you will need to enter your router’s IP in the “Default Gateway” and “Preferred DNS Server” fields.

Once you have RealVNC configured and your internal IP set, you need to configure your router so that the VNC server you have set up is accessible from outside your network. This step varies from router to router depending on the manufacturer, but always involves logging into the web-based control panel and configuring port forwarding. The following steps and included screenshots may be a bit different based on your router.
- Log into your router’s control panel by entering it’s IP (usually 192.168.1.1 by default) into the address bar of your preferred web browser. The username and password should have been set during router setup.
- Find the configuration page for port forwarding.
- Add a new service to your port forwarding table, using port 5900 (the default port for VNC) as both the starting port and the ending port, and ensuring that the IP that the traffic is being forwarded to is the same IP that you configured in the previous step.
- Apply your changes. Please note that this may cause your router to restart.
Now you are able to use a VNC client to connect to your home computer by entering your external IP address (assigned by your ISP and viewable by using WhatIsMyIP.com) and entering your password. However, there is one issue; most ISP’s issue dynamic IPs. This means that your external IP (not to be confused with the internal one you set earlier) changes every so often. Further, this would mean that you could potentially loose access to your VNC setup at any given time. The way to work around this would be to set up a dynamic-DNS service.
- First, you will need to register an account with a dynamic DNS provider such as DynDNS. This process involves choosing a sub-domain which will be configured to point to your IP address; even when it changes.
- Once you have your account, you need to either configure your router, or download a special “updater utility” from your provider’s website. Most routers have a dynamic DNS updating utility built in, and you simply need to enter your given sub-domain and credentials. Your provider should have more information as to configuring your router or their given client for updating.
Now, with all of your configurations done, simply entering your DynDNS sub domain (e.g. mysubdomain.dyndns.info) into your VNC client should bring you to the login screen and ultimately allow you to remote control your computer.
If you find that you made an error or cannot get the setup to work, feel free to post your questions on the forums or in chat. You may also consider using a “zero configuration” remote desktop solution such as LogMeIn or TeamViewer.

Please click below for the latest pc/MRP Manual | Please click below to reach the pc/MRP Main Page |
15.8.1 Overview
A program named VNC can be used for the following purposes:
·Allow you to access a computer at work to use pc/MRP or any other application.
·Allow a remote location to access a computer at work to use pc/MRP.
·Allow technical support at Software Arts to access and trouble shoot pc/MRP.
15.8.2 Requirements
Both the PC at work (should be a workstation and not the server) and the remote PC must have WinVNC installed, and both must have an available internet connection.
15.8.3 Installation
You can download VNC from pc/MRP’s website at http://www.pcmrp.com/download.htm. Scroll down to and download the file ‘vnc-4.0-x86_win32.exe’ into a folder named VNC. (This file is also on the newer install CDs sent out by Software Arts, Inc.) You may at this time install the VNC server by double clicking on the vnc-4.0-x86_win32.exe file and the files will extract it to a folder named C:Program FilesRealVNCVNC4. Install and set-up the VNC Server program. The default settings screen may be displayed. Enter a password and leave the remaining settings in their default mode.
15.8.4 Running VNC
To allow pc/MRP access to a computer, click on Window’s Start Button, select Programs, select VNC, and select Run VNC (UserMode). VNC will start and display a small icon containing the letters VNC in your lower task bar. Placing your cursor over the icon will display your computer’s IP address. The remote computer trying to access this computer will need both the password and the IP address.
To access a remote computer, click on Window’s Start Button, select Programs, select VNC, and select Run VNC Viewer, enter the remote computer’s IP address and password when prompted. If you are running over a slow dial up line, you can speed up screen displays by selecting Options, and check Restrict pixels to 8 bit.
15.8.5 Ports for VNC
Screens Vnc Remote Access To Your Computer 3 8 42
VNC & Ultra VNC require ports 5800 and 5900 to be open on routers connected to the Internet.
