Filters allow you to control Internet access from networked computers. Options allow you to restrict
access to specific web sites, restrict access to all web sites except those you designate, or restrict
access to other computers on your local area network (LAN). There are four types of filters:
• IP filters: Prohibit Internet access by particular LAN IP addresses (see below).
• MAC filters: Prohibit Internet access or LAN access by specific computers (see page 25).
• URL blocking: Prohibit access to groups of web sites by key word (see page 26).
• Domain blocking: Prohibit access to web sites specified by name (see page 27).
