CHAPTER 9 Firewalls 9.1 Overview This chapter shows you how to enable and configure the P-792H v2 firewall. Use these screens to enable and configure the firewall that protects your P-792H v2 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 49 Default Firewall Action LAN 1 A 2 WAN 3 4 9.1.1 What You Can Do in the Firewall Screens • Use the General screen (Section 9.2 on page 122) to enable firewall and/or triangle route on the P-792H v2, 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 9.3 on page 124) to view the configured firewall rules and add, edit or remove a firewall rule.
