Appendix A: Glossary
Encryption
Setting encryption can help keep your network secure. The Router uses Wired
Equivalent Privacy (WEP) encryption to protect your data and features two rates
of encryption: 64-bit and 128-bit. Encryption works on a system of keys. The
key on the computer must match the key on the Router, and there are two ways
to make a key. The easiest is to let the Router’s software convert a passphrase
you’ve created into a key. The advanced method is to enter the keys manually.
Application Gateways
Application gateways let you specify specific ports to be open for specific
applications to work properly with the Network Address Translation (NAT) feature
of the Router. A list of popular applications has been included. You can select
an application from the popular choices included in the drop-down list. Your
selections will be programmed into the Router. From the drop-down list, select
the row that you want to copy the settings from, and the row you want to copy
to, and then click “Copy To”. The settings will be transferred to the row you
specified. Click “Apply Changes” to save the setting for that application. If your
application is not here, you will need to check with the application vendor to
determine which ports need to be configured. You can manually input this port
information into the Router.
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 settings, enter the IP address in the space provided for the
internal machine, the port type (TCP or UDP), and the LAN and public port(s)
required to pass. Then select “Enable” and click “Set”. You can only pass one
port per internal IP address. Opening ports in your firewall can pose a security
risk. You can enable and disable settings very quickly. It is recommended that
you disable the settings when you are not using a specific application.
Client IP Filters
The Router can be configured to restrict access to the Internet, email, or other
network services at specific days and times. Restriction can be set for a single
computer, a range of computers, or multiple computers.
