I have not used that "wg" command (I do not remember to which pkgsrc package it does belong to cause it was some time ago when I was strugling with this). I have used only the "wgconfig" command 
present on the NetBSD base system.

NetBSD implementation does not have the Keepalive setting, I think. That is why I used some periodical pings to keep it alive. Without that and after seveeral seconds my RPiZero was not reachable from 
outside.
