Reverse mapping information can be obtained using the following command:
tools dump nat deterministic-mapping outside-ip <ipv4-address> router <router-instance> outside-port <[1..65535]>
<ipv4-address> : a.b.c.d
<router-instance> : <router-name> | <service-id>
router-name - "Base"
service-id - [1..2147483647]
Example:
tools dump nat deterministic-mapping outside-ip 10.0.0.2 router "Base" outside-port 2333
Output:
Inside router 10 ip 10.0.5.171 -- outside router Base ip 10.0.0.2 port 2333 at Mon Jan 7 10:02:02 PST 2013
