Block Network Access for Game? (lemmy.ml)

I know there are some tools including firejail and bindtointerface on standard Linux Distros, but they don't run in userland, so whenever the deck updates they will be overwritten.

Anyone have any ideas how to block access on a Steam Deck?

Have you tried OpenSnitch

Thanks for the suggestion, I think the main issue is doing it on the Steam Deck. On a native Linux machine it's easier. I don't see a way to install OpenSnitch on the Steam Deck with the read-only file system and whatnot. I think a pi-hole and block DNS might be easier than trying to mess with SteamOS.

You can't install applications on steam deck and there is a read only file system???? Whaaaatttt???????

Edit: I asked a friend that has a steam deck, he explained you can easily disable the read-only system, do whatever you want on a Linux system and reenable it afterwards.

From what i understand any changes to the system outside of the userland will be overwritten after a SteamOS update.

That is correct. The best case is to write a script to make your desired changes, and then run it after each system update.
My own use-case is that I have a NFS mount-point for my Steam Deck to use extra storage on my NAS. After the first time I figured out how to get it mounted, I made a script to disable read-only filesystem, make all the changes to the system, and then re-enable read-only filesystem. After every system update, I just run that script once.
