Chapter 6
Router and Network Management
This chapter describes how to use the network management features of your ProSafe Wireless
ADSL Modem VPN Firewall Router. These features can be found by clicking on the appropriate
heading in the Main Menu of the browser interface.
The ProSafe Wireless ADSL Modem VPN Firewall Router offers many tools for managing the
network traffic to optimize its performance. You can also control administrator access, be alerted
to important events requiring prompt action, monitor the firewall status, perform diagnostics, and
manage the firewall configuration file.
Performance Management
Performance management consists of controlling the traffic through the ProSafe DGFV338 so that
the necessary traffic gets through when there is a bottleneck and either reducing unnecessary
traffic or rescheduling some traffic to low-peak times to prevent bottlenecks from occurring in the
first place. The ProSafe DGFV338 has the necessary features and tools to help the network
manager accomplish these goals.
Wireless Firewall Features That Reduce Traffic
Features of the wireless firewall that can be called upon to decrease WAN-side loading are as
follows:
•
Service blocking
•
Block sites
•
Source MAC filtering

Service Blocking
You can control specific outbound traffic (i.e., from LAN to WAN and from DMZ to WAN).
Outbound Services lists all existing rules for outbound traffic. If you have not defined any rules,
only the default rule will be listed. The default rule allows all outgoing traffic.
Each rule lets you specify the desired action for the connections covered by the rule:
•
BLOCK always
•
BLOCK by schedule, otherwise Allow
•
ALLOW always
•
ALLOW by schedule, otherwise Block
As you define your firewall rules, you can further refine their application according to the
following criteria:
•
LAN users
. These settings determine which computers on your network are affected by this
rule. Select the desired options:
–
Any: All PCs and devices on your LAN.
–
Single address: The rule will be applied to the address of a particular PC.
–
Address range: The rule is applied to a range of addresses.
–
Groups: The rule is applied to a Group. You use the Network Database to assign PCs to
Groups (see
“Groups and Hosts” on page 6-3
).
•
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 by this rule. If the
desired service or application does not appear in the list, you must define it using the Services
menu (see
“Services” on page 6-3
).
•
Schedule
. You can specify whether the rule is to be applied on the Schedule 1, Schedule 2, or
Schedule 3 time schedule (see
“Schedule” on page 6-3
).
Note:
This feature is for Advanced Administrators only! Incorrect configuration will
cause serious problems.
