Except it's not. SNATP2P is not a configurable target. Doh. OK, fine. As every other iptables command, it applies to the specified table (filter is the default), so NAT rules get listed by iptables -t nat -n -L Please note that it is often used with the -n option, in order to avoid long reverse DNS lookups. Destination NAT with netfilter is commonly used to publish a service from an internal RFC 1918 network to a publicly accessible IP. To enable DNAT, at least one iptables command is required. Like every other iptables command, it applies to the specified table (filter is the default), so NAT rules get listed by iptables -t nat -n -L Please note that it is often used with the -n option, in order to avoid long reverse DNS lookups.
