NAT Commands

Network Address Translation (NAT) commands are used to enable or disable NAT on an interface or sub-interface and specify whether IP addresses on the interface are public or private.

Table C-8. NAT Commands (1 of 3)

[no] ip nat {inside outside}

Minimum Access Level: Administrator

Command Mode: config-if, config-subif

Allows you to specify if Network Address Translation (NAT) is performed on an interface or sub-interface and whether IP addresses on the interface are private or public addresses. NAT is disabled by default.

Example: ip nat inside

ip nat translation timeout [time ]

no ip nat translation timeout [time]

Minimum Access Level: Administrator

Allows you to specify the amount of time that a dynamically configured standard NAT (non-port translation) mapping can remain unused before the mapping is automatically deleted.

The default is 24 hours. To reset the timeout to the default, use the no nat translation timeout command.

Example: ip nat translation timeout 604800

NOTE: When NAPT is enabled, mappings are automatically deleted based on a separate set of non-configurable timeouts:

–UDP translations timeout: 5 minutes.

–TCP translations timeout: 24 hours.

–ICMP translations timeout: 1 minute.

time – The timeout value in seconds. The valid range is 1–2147483647. The default is 86400 seconds (24 hours).
