Docker(-compose) with shorewall

The shorewall documentation explains in http://shorewall.org/Docker.html how to configure shorewall for use with docker. The problem with the configuration is that it only allows connections from the host to the main bridge docker0. Connections to other networks on dynamically created bridges, with names starting by default with br-, is blocked. Instead of the recommended contents of /etc/shorewall/interfaces, use wild-card interface names as follows:

#ZONE	INTERFACE	OPTIONS
#dock	docker0		bridge     # disabled default recommendation
dock 	docker0		physical=docker+,routeback=1
dock 	br		physical=br-+,routeback=1

Installing IPAs on Apple Silicon (M1)

1. Open Apple Configurator 2 and plug in your iPhone or iPad
2. Click Add, login to the App Store and select the application you want to install
3. Open up ~/Library/Group\ Containers/K36BKF7T3D.group.com.apple.configurator/Library/Caches/Assets and wait until the TemporaryItems directory appears
4. Copy the application from the newly created temporary directory, but do note that it will disappear once Apple Configurator is done installing
5. Double click the .ipa on your Apple Silicon (M1) device and install it
6. Fix permissions on the installed application by running sudo xattr -rd com.apple.quarantine /Applications/<your_app>.app (if you skip this step, you're unable to start the application)

Note that it's easier if you already have the application installed, as Apple Configurator will prompt you about overwriting the existing installation, at which point the temporary file (the .ipa) will still exist, until you choose an action in the prompt.
