CHAPTER 12 Security 12.1 Overview Use these screens to enable and configure the firewall that protects your NBG6818 and your LAN from unwanted or malicious traffic. Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and control access between the LAN and WAN. By default the firewall: • allows traffic that originates from your LAN computers to go to all of the networks. • blocks traffic that originates on the 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 72 Default Firewall Action Note: Features in this chapter are not available if you are using bridge mode. 12.1.1 What You Can Do • Use the IPv4 Firewall screen to enable or disable the NBG6818's IPv4 firewall (Section 12.2 on page 124). • Use the IPv6 Firewall screen to enable or disable the NBG6818's IPv6 firewall (Section 12.3 on page 127). 12.1.2 What You Need To Know The following terms and concepts may help as you read through this chapter.
