Chapter 20 Introduction 101 Banning computer connections You can add, edit, and remove banned IP addresses in the Trusted and Banned IPs pane, under Banned IP Addresses. Computers that are associated with unknown, suspicious, or distrusted IP addresses can be banned from connecting to your computer. Since Firewall blocks all unwanted traffic, it is normally not necessary to ban an IP address. You should ban an IP address only when you are certain an Internet connection poses a specific threat. Ensure that you do not block important IP addresses, such as your DNS or DHCP server, or other ISP-related servers. Depending on your security settings, Firewall can alert you when it detects an event from a banned computer. Add a banned computer connection You can add a banned computer connection and its associated IP address. Note: Ensure that you do not block important IP addresses, such as your DNS or DHCP server, or other ISP-related servers. 1 On the McAfee SecurityCenter pane, click Internet & Network, then click Configure. 2 On the Internet & Network Configuration pane, under Firewall protection is enabled, click Advanced. 3 On the Firewall pane, click Trusted and Banned IPs. 4 On the Trusted and Banned IPs pane, select Banned IP Addresses, and then click Add. 5 Under Add Banned IP Address Rule, do one of the following: ƒ Select Single IP Address, and then enter the IP address. ƒ Select IP Address Range, and then enter the starting and ending IP addresses in the From IP Address and To IP Address boxes. 6 Optionally, select Rule expires in, and enter the number of days to enforce the rule. 7 Optionally, type a description for the rule. 8 Click OK. 9 On the Trusted and Banned IPs dialog, click Yes to confirm.
