Only one iptables rule is needed. As first rule in the iptables list, match
all packets with 1. Then process the rules in the iptables list and mark the
packets with an other mark if you want. All packets not matched again, will
keep the mark 1. This is your "default" mark.
You only need a filter to put the packets marked with 1 in a default class and
you have your default filter.
