ProSafe Dual WAN Gigabit Firewall with SSL & IPsec VPN FVS336G Reference Manual Groups and Hosts You can apply these rules selectively to groups of PCs to reduce the outbound or inbound traffic. The LAN Groups 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 VPN firewall 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 LAN Groups 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 ARP. requests. The ARP scan will detect active devices that are not DHCP clients. However, sometimes the name of the PC or device cannot be accurately determined, and will appear in the database as Unknown. • Manual Entry. You can manually enter information about a device. See "Managing Groups and Hosts (LAN Groups)" on page 3-5 for the procedure on how to use this feature. Schedule If you have set firewall rules on the Rules screen, you can configure three different schedules (for example, 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. See "Setting a Schedule to Block or Allow Specific Traffic" on page 4-29 for the procedure on how to use this feature. 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 (i.e., 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. 8-4 Router and Network Management v1.2, June 2008

Router and Network Management
v1.2, June 2008
Groups and Hosts
You can apply these rules selectively to groups of PCs to reduce the outbound or inbound traffic.
The LAN Groups 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 VPN firewall 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 LAN Groups 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 ARP. requests. The ARP scan will
detect active devices that are not DHCP clients. However, sometimes the name of the PC or
device cannot be accurately determined, and will appear in the database as Unknown.
Manual Entry
. You can manually enter information about a device.
See
“Managing Groups and Hosts (LAN Groups)” on page 3-5
for the procedure on how to use
this feature.
Schedule
If you have set firewall rules on the Rules screen, you can configure three different schedules (for
example, 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.
See
“Setting a Schedule to Block or Allow Specific Traffic” on page 4-29
for the procedure on
how to use this feature.
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 (i.e., 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.
