Hi, a howto from Russel describes a reboot clears all created chains concerning the kernel routing. So I tried this but it's not working: $IPTABLES -F # flush aller chains (Tabelle filter) $IPTABLES -X # delete all userdefined chains $IPTABLES -t nat -F # flush aller chains (Tabelle nat) All chains are deleted (iptables -L) but my routing is not working properly while using masquerade. How can I overcome this problem to avoid a reboot while using iptables ? -- Best Regards, Mark
