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 Web sites with other domain suffixes (such as .edu or 
.gov) can be viewed.

•

If you wish to block all Internet browsing access, enter the keyword “.”.

To specify a Trusted User, enter that PC’s IP address in the Trusted User box and click Apply.

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.

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 FVS318v3 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.
