Currently this can be done iptables -t mangle -I PREROUTING -m connlabel --label portforward What if someone wants to use multiple labels? One would have to write this same rules several times. Can we do something like this: iptables -t mangle -I PREROUTING -m connlabel --label portforward-something-somethingelse-... This way multiple labels can be used with a single rule. Is this possible to do, or is there any workaround for this?
