How to play zombies with my friends privately

[JesproGG]

I would like to know if there is any way to connect with my friends to zombie games and be alone without anyone else joining

if u want to play private match with ur friends then u gotta turn on uPnP and port forward on ur router. then if i'm correct, ur friends need to join ur through IP address if i'm correct
