You can do iptables -t mangle -N mark5 for a in 192.100.100.8 10.254.253.1 172.16.0.1; do iptables -t mangle -A mark5 -d $a -j RETURN done iptables -t mangle -A mark5 -j MARK --set-mark 5 iptables -t mangle -I PREROUTING -s 10.10.10.10 -j mark5 Or maybe it will suffice to first mark all packets from 10.10.10.10 with mark 5 and then remark packets with those three destinations back to 0 (or anything else).
