show running-config nat
Shows the NAT configuration.
Note You cannot view the NAT configuration using the show
running-config object command. You cannot reference objects
or object groups that have not yet been created in nat commands.
To avoid forward or circular references in show command output,
the show running-config command shows the object command
two times: first, where the IP address(es) are defined; and later,
where the nat command is defined. This command output
guarantees that objects are defined first, then object groups, and
finally NAT. For example:
hostname# show running-config
...
object network obj1
range 192.168.49.1 192.150.49.100
object network obj2
object 192.168.49.100
object network network-1
subnet <network-1>
object network network-2
subnet <network-2>
object-group network pool
network-object object obj1
network-object object obj2
...
object network network-1
nat (inside,outside) dynamic pool
object network network-2
nat (inside,outside) dynamic pool
show xlate
