The ESET firewall acts as a network traffic filter that regulates communication within the local network or the internet. Using predefined rules, the firewall analyzes network communication and decides whether or not to allow it. You can configure your firewall to make exceptions for certain applications.
Press the F5 key on your keyboard to access Advanced setup.
Click Network Protection → Firewall, expand Advanced and click Edit next to Rules.
