The solution was very simple: iptables -t nat -A PREROUTING -i eth0 --source 10.5.1.0/24 -p udp --dport 69 -j REDIRECT --to-port 20001 iptables -t nat -A PREROUTING -i eth0 --source 10.5.2.0/24 -p udp --dport 69 -j REDIRECT --to-port 20002 Thanks for the advices Thomas -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
