[RESOLVED] WINE apps and Firewall

[Princey]

I do know how to allow or block a Linux app in the firewall via command line. My question though is in relation to applications installed via WINE. Is the process similar for example?

sudo ufw allow/deny application.exe

There are a few Windows games I play via WINE that are "free" albeit with a price tag of annoying ads popups. They're not multiplayer games so there's no reason to be dialing out. I know I can set the firewall to restrict all apps except those I allow. Of course, that would cost me much more time specifying firewall rules and I run the risk of accidentally blocking a port I wasn't supposed to. (If it was a server, I wouldn't mind as that's how I configure servers). But for a standalone desktop, I don't find the hassle necessary. Any ideas?

Ufw doesn't block applications , at least not directly. Just ports and services.

Firejail may be the best and most popular choice

Opensnitch may be another

Thanks Claydoh. I think opensnitch looks like the best alternative as I don't want block WINE altogether, just a few annoying games that I love and hate at the same time.

Just be aware that executables for wine won't be very obvious, and that for the purposes of a firewall, you might need to block wine. I have no idea, though.

So far, they do show up under processes if I open system monitor. Are you saying that it's not enough to block such executables?

I have no idea. I'll assume that the executables run, but no I'm idea if wine's libraries affect anything, in terms of networking or access.
