• Application Level Gateways (ALGs). Applications which use non-standard
connections or port numbers are normally blocked by the Firewall. The ability to
define and allow such applications is provided, to enable such applications to be
used normally.

use Internet applications which normally do not function when used behind a fire-
wall.

Virtual Servers. This feature allows Internet users to access Internet servers
on your LAN. The required setup is quick and easy.
•
Dynamic DNS Support. DDNS, when used with the Virtual Servers feature,
allows users to connect to Servers on your LAN using a Domain Name, even if
you have a dynamic IP address which changes every time you connect.
•
URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN
users.
•
Firewall. As well as the built-in firewall to protect your LAN, you can define
Firewall Rules to determine which incoming and outgoing traffic should be permit-
ted.

Scheduling. Both the URL Filter and Firewall rules can be scheduled to operate
only at certain times. This provides great flexibility in controlling Internet -bound
traffic.

Syslog Server. Log data can also be E-mailed to you.
