Description-en: Source-natting firewall logging utility
Firewalls like iptables usually offer POSTROUTING source network address
translation facilities changing the source address of a host behind the
firewall to the address of the host before the firewall.
.
The standard log facilities provided by iptables do not easily allow us to
associate addresses behind the firewall to their source-natted equivalents
before the firewall. Natlog was designed to fill in that particular niche.
.
When running natlog, messages are sent to the syslog daemon and/or to the
standard output stream showing the essential characteristics of the
connection using source natting. Here is an example:
.
from Fri 8 22:30:10:55588 until Fri 8 22:40:43:807100: 192.168.19.72:4467
(via: 129.125.90.132:4467) to 200.49.219.180:443
.
Natlog depends on facilities provided by iptables; work is in progress to
generate logs using facilities offered by the pcap library.
