[gentoo-user] How to hide a network interface from an application

[Grant Edwards]

How does one hide a network interface from a badly-written application?

I'm using Plex Media Server as a DVR, it it seems to have been written
by Windows programmers who assume that your computer exists for no
purpose other than running their program and their program alone.  It
spews multicast and broadcast packets on all network interfaces
regardless of which interface you configure it to use.

Is creating a network namespace that contains only the interfaces Plex
is allowed to use the best way to try to fix this problem?  [Assuming
the developers won't do anything about it.]
