i am having trouble with ipv6 in a specific program. (sf6 steam version)
completely disabling it has resolved my issues.
but this solution just doesn’t sit well with me.
is there a way to only block that one problematic program from using ipv6?

Nobody out there seems to know how to do IPv6 properly. Lots of issues just went away when I disabled it on my “end user” subnets.
Harsh but true.

with iptables you could block the port used by this app, but maybe it would not fix your problem

You could just setup a separate namepace with IPv6 disabled and move the process into it. I’d be more detailed, but this comment is one eyed and very sleepy, let us know how you go.

Seconding this. Take a look at the unshare program and user namespaces.

You can install ufw and a frontend for it that lets you block specific processes. https://wiki.archlinux.org/title/Uncomplicated_Firewall#GUI_frontends It seems KDE already comes with a frontend in the system settings, and there’s gufw for gnome/gtk.

I feel selinux should be able to do something clever here, like it can manage/block port access.
