USING THE WEB-BASED ADVANCED USER INTERFACE
The firewall also masks common ports that are frequently used to
attack networks. These ports appear to be “stealth” meaning that for
all intents and purposes, they do not exist to a would-be hacker. You
can turn the firewall function off if needed; however, it is recommended
that you leave the firewall enabled. Disabling the firewall protection will
not leave your network completely vulnerable to hacker attacks, but it is
recommended that you leave the firewall enabled.
Configuring Internal Forwarding Settings
The Virtual Servers function will allow you to route external (Internet)
calls for services such as a web server (port 80), FTP server (Port 21), or
other applications through your Router to your internal network. Since
your internal computers are protected by a firewall, computers outside
your network (over the Internet) cannot get to them because they cannot
be “seen”. A list of common applications has been provided in case you
need to configure the Virtual Server function for a specific application.
If your application is not listed, you will need to contact the application
vendor to find out which port settings you need.
