Debuging NAT on ASA

SDWorx_2
Level 1
Level 1

Hi,

I don't know this is possible (I can't find it how) but I would like to debug all translations the ASA performs. I would like to view in realtime all translations.

Show xlate is a way to view translations I guess, but it is not what I was looking for.

Is there any way I can get this done?

Thank you,

Jan

To display active Network Address Translation (NAT) translations, use the "show ip nat translations" command in EXEC mode.

Refer the following url for more info:

What Shumon suggested will only work on routers. With the new ASA's I have not been able to find a command to debug NAT.

show local-host, show connection could help even they're not exclusively related to NAT.

You could also use the command :

"logging list event_list message start" with the Message 202001 (out of translation slots) and messages 305009 through

305011 (translations built and torn down)

I'm also unaware of any command that can help you debug NAT. You can use the following tough:

show xlate [det | debug]

show conn det [all]

show local-host [all]

show nat

I would like to inform you that this can be checked with the command :

“show xlate global <ip address>”
