Commands

List Rules

iptables -L -nv --line-numbers

The command list all rules in the selected chain. If no chain is selected, all chains are listed.

The command applies to the specified table (filter is the default). If you need to list rules from a table other than "filter", use -t (example -t nat).

Please note that it is often used with the -n option, in order to avoid long reverse DNS lookups.
