Using Rules To Block Or Allow Specific Kinds Of Traffic - NETGEAR FWG114P Reference Manual

Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
Keyword application examples:
• If the keyword "XXX" is specified, the URL <http://www.badstuff.com/xxx.html> is blocked,
as is the newsgroup alt.pictures.XXX.
• If the keyword ".com" is specified, only websites with other domain suffixes (such as .edu or
.gov) can be viewed.
• If you want to block all Internet browsing access, enter the keyword ".".
To specify a Trusted User, enter that computer's IP address in the Trusted User box and click
Apply.
You may specify one Trusted User, which is a computer that will be exempt from blocking and
logging. Since the Trusted User will be identified by an IP address, you should configure that
computer 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 of the
wireless firewall/print server 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 FWG114P 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.
