Q19: How to use remote control software such as VNC, pcAnywhere, LapLink, Terminal Server, etc.

We will point out three different cases.

  1. You work on a computer located on a LAN and connected to the Internet via WOOWEB-PRO. You want to take control over a remote computer, which is directly connected to the Internet by a modem.
  2. You work on a remote computer and you want to view and control a computer located on a LAN and connected to the Internet via WOOWEB-PRO.
  3. The two computers access the Internet via WOOWEB-PRO.

The first case does not make any problem. No special setup is required. Cases 2 and 3 are similar and need some modification of the WOOWEB-PRO settings.

Remote control applications generally use one or several TCP/UDP ports. These ports may be fixed or configurable values. Here is a non exhaustive list of default TCP/UDP ports used by remote control applications.

Software Application TCP/UDP Port Usage
VNC 5900 and 5800
pcAnywhere till version 7.51 65301
pcAnywhere from version 7.52 5631 and 5632
LapLink 1547
 Microsoft Terminal Server or Remote Desktop Connection  3389

To set up WOOWEB-PRO, proceed as following:

  1. Refer to the editor documentation to know the TCP/UDP ports used by the application.
  2. Make sure there is no protocol limitation on the Internet connection. To do that, select "Settings..Connections..Properties..Filtering" and check "Allow all IP protocols".
  3. You must then give access to remote users. Open "Settings..Remote Filters".
  4. Select "Allow the remote users according to the following rules" and add a filter that will authorize the remote users allowed to take control over the local computer.
  5. Tell WOOWEB-PRO which local machine is to be accessed from the Internet. To do that, in the "Destination" tab, fill in the "Map the Internet Client To the Local Computer" section, the IP address or name of computer where the remote control application is installed. 
  6. In the "Port/Protocol" tab, validate the remote TCP/UDP ports. To do that, select either "Allow Accesses to All Ports and Protocols" or "Allow accesses only to the Checked Following Port Ranges and Protocol Numbers". in this last case, in the "Selected Port Range and Protocol Number" box, enter the application name and fill the port range. Click "Add" and make sure the new port name is checked in the port list.
  7. Validate the filter and make sure it is checked in the "Remote Filters" dialog.
