The numbers are Packets:Bytes that have matched. If you have several rules (instead of simply a DROP policy for the chain) this will show you how much traffic matched each rule. You shouldn't manually edit it, but if you want to reset it use "iptables -Z" (to zero the counts for the default table, filter) and/or "iptables -t nat -Z". (to zero counts for the NAT table) If you list the active rules with "iptables -v -n -L" it will list all the filter table rules along with packets and bytes that matched each, and here again "-t nat" will specify the nat table instead of the default filter table. j > Thanks. > > Chi
