If you are applying new rules via a script, you need to first flush all existing chains, then delete the additional chains, otherwise you will try to create a chain that already exists... >From the turorial at http://www.netfilter.org/documentation/tutorials/blueflux/ # # flush all the rules in the filter and nat tables. # $IPTABLES -F $IPTABLES -t nat -F $IPTABLES -t mangle -F # # erase all chains that's not default in filter and nat table. # $IPTABLES -X $IPTABLES -t nat -X $IPTABLES -t mangle -X
