tool that display NAT connections
Netstat-nat is a program that displays Network Address Translations (NAT) connections, managed by netfilter/iptables acting as firewall.
NAT rules are stored in memory. However, the program reads its information from '/proc/net/ip_conntrack', which is the temporary conntrack-storage of netfilter.
