Services. The Rules menu contains a list of predefined Services for creating firewall rules. If a
service does not appear in the predefined Services list, you can define the service. The new service
will then appear in the Rules menu's Services list.
See "Services-Based Rules" on page 4-2
Groups and Hosts. You can apply these rules selectively to groups of PCs to reduce the
outbound or inbound traffic. The Network Database is an automatically-maintained list of all
known PCs and network devices. PCs and devices become known by the following methods:
• DHCP Client Request – By default, the DHCP server in this Router is enabled, and will
accept and respond to DHCP client requests from PCs and other network devices. These
requests also generate an entry in the Network Database. Because of this, leaving the DHCP
Server feature (on the LAN screen) enabled is strongly recommended.
• Scanning the Network – The local network is scanned using standard methods such as ARP.
This will detect active devices which are not DHCP clients. However, sometimes the name of
the PC or device cannot be accurately determined, and will be shown as Unknown.
See "Managing Groups and Hosts" on page
Schedule. If you have set firewall rules on the Rules screen, you can configure three different
schedules (i.e., schedule 1, schedule 2, and schedule 3) for when a rule is to be applied. Once a
schedule is configured, it affects all Rules that use this schedule. You specify the days of the week
and time of day for each schedule.

Block Sites

If you want to reduce traffic by preventing access to certain sites on the Internet, you can use the
VPN firewall's filtering feature. By default, this feature is disabled; all requested traffic from any
Web site is allowed.
• Keyword (and Domain Name) Blocking – You can specify up to 32 words that, should they
appear in the Web site name (URL) or in a newsgroup name, will cause that site or newsgroup
to be blocked by the VPN firewall.
You can apply the keywords to one or more groups. Requests from the PCs in the groups for
which keyword blocking has been enabled will be blocked. Blocking does not occur for the
PCs that are in the groups for which keyword blocking has not been enabled.
