ProSafe Gigabit 8 Port VPN Firewall FVS318G Reference Manual
VPN Firewall and Network Management 6-3
v1.1, August 2010
• WAN Users. These settings determine which Internet locations are covered by the rule, based
on their IP address.
– Any. The rule applies to all Internet IP address.
– Single address. The rule applies to a single Internet IP address.
– Address range. The rule is applied to a range of Internet IP addresses.
• Services. You can specify the desired services or applications to be covered a rule. If the
desired service or application does not appear in the list, you must define it using the Services
screen (see “Adding Customized Services” on page 4-24).
• 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 the 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 Network Database. Because of this, leaving
the DHCP Server feature (on the LAN Setup 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.
– 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 one of the the LAN WAN Rules screen and the
DMZ WAN Rules screen, you can configure three different schedules (that is, 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.)
Blocking 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
website is allowed.
