Hello,

I'm wondering if there is a better way to show the logging in the realtime logger. Currently it only shows outbound nat translations and nothing more

severity, date, time, syslog id, source ip, source port, destination ip, destination port, description

6 Mar 12 2013 18:17:49 305011 172.16.0.101 62193 216.2.7.68 62193 Built dynamic UDP translation from inside:172.16.0.101/62193 to outside:216.2.7.68/62193

I would like to be able to view the destination IP that 172.16.0.101 is trying to reach and not just my public ip address, but to do this I have to use the packet capture wizard each time and open up wireshark each time to view the traffic. There must be a better way.

Thanks,

Dan.

Check for these logs, "ASA-6-302013"

ASA-6-302013: Built {inbound|outbound} TCP connection_id for interface:real-address/real-port (mapped-address/mapped-port) to interface:real-address/real-port (mapped-address/mapped-port) [(user)]

I see none of those. Only ASA-6-305011 Built and ASA-6-305012 Teardown

And all of these messages only show my private IP and my public IP not the actual destination.

Mind sharing the output of the "show run logging" command from the ASA?

Some people prefer to stop logging certain messages when they get a lot of information or just a lot of logs.

Depending on the scenario, too many logs can represent a problem with CPU resources and sometimes bandwidth.

If you know your network like you know your facebook contacts [insert laughs here] i would recommend you to leave it like this until you understand the real purpose of the commands or have a little chat with the person that configured the unit.
