Logging NAT Translations on the Cisco ASA
It’s often handy when dealing with infringement notices and the like to have NAT translations logged. Sure a better way would be to record netflow from these devices (and include the translations) but for a quick syslog solution, you can always enable by running the following…
logging enable
logging list ToSyslog level critical
logging list ToSyslog message 305011
Messages will look something like:
May 08 13:01:20 freewifi-asa.net.uow.edu.au %ASA-6-305011: Built dynamic TCP translation from inside:10.64.37.96/53008 to outside:192.131.251.2/49520
