So if you find the log ids for the NAT setups and teardowns (see [1]), you can change the severity level of the message -
logging message <message id> level <new level>[1] http://www.cisco.com/en/US/docs/security/asa/asa84/system/message/logmsgs.html

Second the comment re: "insane" level of campus-border firewall logging necessary to respond to lawful requests. We're over 100GB/day across our 60ish campuses. Cisco's ASAs won't log NAT bind - setups and teardowns - unless you go to "debug" level. We do have a few of noisy+useless message IDs which we don't send as well. Dunno how much volume that saves us, though. -jml -----Original Message----- From: The EDUCAUSE Security Constituent Group Listserv [mailto:SECURITY () LISTSERV EDUCAUSE EDU] On Behalf Of Dave G Bulanda Sent: Tuesday, 29 November, 2011 10:44 To: The EDUCAUSE Security Constituent Group Listserv; John Ladwig Subject: Re: [SECURITY] DMCA and NAT Kevin, The way that I handle the DMCA and NAT issue is that I run syslog of my border firewall in a somewhat "INSANE" level.
