Hi
On this movie author shows prioritezation of the services, we are mangling some packet’s, but there is much else traffic that isn’t mangled, what prioritaire have else packet, or how can I catch them?
mark all known with passthrough=no, then mark everything else with one additional rule =)
Isn’t there any other option, to give other traffic mark “other” ?
yep 
the rest are alredy “other”.!!!
ex;
33 ;;; other
chain=prerouting action=mark-packet new-packet-mark=other_in passthrough=no in-interface=wan
34 chain=postrouting action=mark-packet new-packet-mark=other_out passthrough=no out-interface=wan
What you must do is to specify only interface of entry and exit of traffic
regards
