ProSafe Wireless-N VPN Firewall SRXN3205 Reference Manual
VPN Firewall and Network Management 9-3
v1.0, January 2010
• WAN Users. These settings determine which Internet locations are covered by the rule, based
on the 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 5-19).
• 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 Setup 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 LAN WAN 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 Schedules to
Block or Allow Specific Traffic” on page 5-24 for the procedure on how to use this feature.)
