Reference Manual for the Model FWAG114 Cable/DSL Wireless ProSafe Firewall
Firewall Protection and Content Filtering 4-3
You may specify one Trusted User, which is a PC that will be exempt from blocking and
logging. Since the Trusted User will be identified by an IP address, you should configure that
PC with a fixed or reserved IP address.
Using Rules to Block or Allow Specific Kinds of Traffic
Firewall rules are used to block or allow specific traffic passing through from one side to the other.
Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively allowing
only specific outside users to access specific resources. Outbound rules (LAN to WAN) determine
what outside resources local users can have access to.
A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of
the FWAG114 are:
• Inbound: Block all access from outside except responses to requests from the LAN side.
• Outbound: Allow all access from the LAN side to the outside.
These default rules are shown in the Rules table of the Rules menu in
