Firewalls

10.1  Overview

This chapter shows you how to enable and configure the P-660HN-F1A firewall. 
Use these screens to enable and configure the firewall that protects your P-
660HN-F1A and network from attacks by hackers on the Internet and control 
access to it. By default the firewall:

• allows traffic that originates from your LAN computers to go to all other 

networks. 

• blocks traffic that originates on other networks from going to the LAN. 

The following figure illustrates the default firewall action. User A can initiate an IM 
(Instant Messaging) session from the LAN to the WAN (1). Return traffic for this 
session is also allowed (2). However other traffic initiated from the WAN is blocked 
(3 and 4).

Figure 74   

Default Firewall Action

10.1.1  What You Can Do in the Firewall Screens

• Use  the  General screen (

Section 10.2 on page 194

) to enable firewall and/or 

triangle route on the P-660HN-F1A, and set the default action that the firewall 

takes on packets that do not match any of the firewall rules.

• Use  the  Rules screen (

Section 10.3 on page 196

) to view the configured firewall 

rules and add, edit or remove a firewall rule.
