The Personal firewall controls all network traffic to and from the system. This is accomplished by allowing or denying individual network connections based on filtering rules. It provides protection against attacks from remote computers and enables blocking of some services. It also provides antivirus protection for HTTP, POP3 and IMAP protocols. This functionality represents a very important element of computer security.
Personal firewall configuration can be found in the Setup pane under Network protection. Here, you can adjust the filtering mode, rules and detailed settings. You can also access more detailed settings by clicking the gear wheel > Configure... next to Personal firewall, or by pressing F5 to access Advanced setup.
Click the gear wheel next to Personal firewall to access the following settings:
Configure... – Opens the Personal firewall window in Advanced setup where you can define how the firewall will handle network communication.
Pause firewall (allow all traffic) – The opposite of blocking all network traffic. If selected, all Personal firewall filtering options are turned off and all incoming and outgoing connections are permitted. Click Enable firewall to re-enable the firewall While Network traffic filtering is in this mode.
Block all traffic – All inbound and outbound communication will be blocked by the Personal firewall. Only use this option if you suspect a critical security risk that requires the system to be disconnected from the network. While Network traffic filtering is in Block all traffic mode, click Stop blocking all traffic to restore normal firewall operation.
Automatic mode – (when another filtering mode is enabled) – Click to change the filtering mode to automatic filtering mode (with user-defined rules).
Interactive mode – (when another filtering mode is enabled) – Click to change the filtering mode to interactive filtering mode.
Network attack protection (IDS) – Analyzes the content of network traffic and protects from network attacks. Traffic that is considered harmful will be blocked.
Botnet protection – Quickly and accurately spots malware on your system.
Connected networks – Shows the networks to which network adapters are connected. After clicking the link below the network name, you will be prompted to select a protection type (strict or allowed) for the network you are connected to via your network adapter. This setting defines how accessible your computer is to other computers on the network.
Temporary IP address blacklist – View a list of IP addresses that have been detected as the source of attacks and added to the blacklist to block connection for a certain period of time. For more information see the Temporary IP address blacklist chapter.
Troubleshooting wizard – Helps you solve connectivity problems caused by ESET Personal firewall. For more detailed information see Troubleshooting wizard.
