Hello Everyone,
I'd like to see and catch NAT log in my ASR 1006 and then I ran "ip nat log translations syslog". But NAT log doesn't appear when I check " show log". How can do for that?
Here is the Logging command that I've already configure.
logging history size 500
logging history informational
logging origin-id hostname
logging source-interface GigabitEthernet0 vrf Mgmt-intf
Solved! Go to Solution.

Hello
You can check the nat translation table in detail or apply nat debug in detail to either the whole of the NAT translation or specific to a access-list, the debug should be logged into the rtrs logging buffer. console or monitor
sh ip nat translation *
sh ip nat translation verbose
sh ip nat nvi translation *
sh ip nat nvi translation verbose
debug ip nat
debug ip nat >acl>
debug ip nat <acl> detailed
logging buffered informational
