This article explains how to use Apple's Shortcuts app to enable, disable or pause 1Blocker's Firewall depending on such actions as launching an app, connecting to a Wi-Fi network, etc. In other words, with an automation shortcut, you can make Firewall automatically perform actions that normally require launching 1Blocker.
Shortcuts is a default iOS app, so most probably, it's already installed on your iOS or iPadOS device, but you can also download it from the App Store anytime.
