4 Click Apply to save the setting for this application.
Virtual Servers This 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, machines from the Internet cannot
get to them because they cannot be 'seen'.
If you need to configure the Virtual Server function for a specific
application, you will need to contact the application vendor to find out
which port settings you need.
To manually enter Virtual Server settings, do the following:
1 Select Firewall from the main menu, then select Virtual Servers from the
sub-menu. The Virtual Servers screen displays (Figure 35
)

2 Click Add to configure a new Virtual Server entry, or click Edit in the
Configure column to edit an existing entry. The Virtual Server - Add/Edit
screen displays (Figure 36
).
You can delete an existing entry by clicking on delete in the Configure
column.
