Firewall Builder in Breadstick

Breadstick runs Debian's own fwbuilder package for ARM64, the build a Debian 13 computer with an ARM processor installs, so Firewall Builder should look and behave as it does on a Linux PC. On Samsung DeX, Floating mode opens it as its own window beside your Android apps, and Desktop mode runs it on a full Linux desktop.

Linux apps use Android's own network connection, and a VPN connected in Android covers them too. More about internet apps in Breadstick.

About Firewall Builder

From Debian's package description

Firewall Builder consists of an object-oriented GUI and a set of policy compilers for various firewall platforms. In Firewall Builder, firewall policy is a set of rules, each rule consists of abstract objects which represent real network objects and services (hosts, routers, firewalls, networks, protocols). Firewall Builder helps the user maintain a database of objects and allows policy editing using simple drag-and-drop operations.
