nat outbound

nat outbound


The nat outbound command associates an ACL with a NAT address pool. In this manner, the addresses specified in the ACL can be translated using the NAT address pool.

The undo nat outbound command disables outbound NAT.

By default, outbound NAT is disabled.


nat outbound acl-number address-group group-index [ no-pat ]

undo nat outbound acl-number address-group group-index [ no-pat ]






Specifies the number of an ACL.

The value is an integer that ranges from 2000 to 3999.

address-group group-index

Indicates that the NAT address pool is used for address translation. If no NAT address pool is specified, the IP address of the interface is used as the translated IP address. That is, Easy IP is used.

The value is an integer that ranges from 0 to 3.


Indicates one-to-one NAT, that is, only the IP address in a datagram is translated and the port number is not translated.

Usage Guidelines

Use Scenario

After an ACL is associated with a NAT address pool, NAT translates the source IP address of a data packet matching the ACL to an IP address in the NAT address pool.

On the same interface, different IP addresses can be translated and associated. This interface usually connects to an ISP network and is the egress of the internal network.

This command can only be used on Layer 3 interfaces, except the Loopback and NULL interfaces.


# Select the addresses from to to form NAT address pool 1, and configure the hosts in the network segment to use the addresses in address pool 1 for many-to-one address translation (using TCP/UDP port information).
