This is my problem. I have configured iptables for modifying ip source of syslog packets outgoing from one of my router interfaces. I have used these commands: iptables -t mangle -A OUTPUT -p udp --dport 514 -j MARK --set-mark 13 iptables -t nat -A POSTROUTING -m mark --mark 13 -j SNAT --to-source 2.2.2.2 With the commands iptables -t nat -L iptables -t mangle -L I can see that the previous rules have been correctly inserted and the syslog packets have the right ip source. If I delete the previuos rules, I have no effect on syslog traffic and also if I give new iptables command with different ip source (Es. iptables -t nat -A POSTROUTING -m mark --mark 13 -j SNAT --to- source 3.3.3.3) syslog pkt maintains the previous ip source (2.2.2.2) while no rule is configured with this ip. Is there some iptables options that I have to give to force the rules updating? Thanks a lot for your collaboration! Monia Cheli La gara più entusiasmante dell'anno!
