Why do many Windows games fail when the network is sandboxed?
I run Windows games with Wine, and use
bwrap to sandbox them. I've noticed that passing
--unshare-net to disable the network breaks many, many games (they fail to start with no obvious error message). However, at the same time, if I do
nmcli networking off instead of
--unshare-net the game launches fine.
--unshare-net crash a Windows program on launch, and how can I block internet access from inside bwrap?
