Firewalls

 

A firewall is a computer networking component used to create a barrier between two networks.  Most commonly, a firewall selectively separates a home or business (internal) network from the Internet (or other external network).  A firewall is a security measure designed primarily to prevent unwanted access by someone on the Internet to a private network.  The firewall can also be used to prevent access to specific computers on the Internet.

 

Firewalls can be implemented using software or hardware. Hardware firewalls are usually an integrated function in a network router. Hardware firewalls are considerably faster (and more expensive) than software firewalls. 

 

Unlike previous versions of Microsoft^® Windows^® operating systems, Windows^® XP provides built-in firewall software.  Firewall software must be purchased as a separate item and then installed and configured, if you are not using the Windows^® XP operating system firewall software.

 

To set up your firewall to work with e-Surveiller, perform the following operations on both the Station and monitored computers:

 

             1     Take note of the e-Surveiller Port. You can see this by opening the e-Surveiller Station (on the Station Computer), selecting Settings from the View menu and clicking the connection tab.

             2     Configure your firewall software or hardware to allow incoming and outgoing connections on the e-Surveiller port.

             3     Configure your firewall software to enable outgoing connections on the IRC (6667) and Gnutella ports (6346) and incoming connections on the ident port (113)

       NOTE: The ports for the IRC and Gnutella networks the station connects to may not be 6667 and 6346. To see what port numbers the station connects to; check the connections tab in the station settings window.

 

  NOTE: For detailed information on opening ports in the Windows^® XP firewall, visit the How to manually open ports in Internet Connection Firewall in Windows XP support page.
