.... The UniFi Security Gateway (USG) offers administrators many useful features to manage their UniFi network, including the ability to create and manage firewall rules that help ensure the security of the network. This guide will explain how to configure firewall rules in the UniFi Network Controller and offer some suggestions for managing the firewall using the USG.
