Table C-8. NAT Commands (2 of 3)

ip nat pool pool-name start-ip-addr end-ip-addr

{netmask netmask { prefix-length /} prefix-length}

no ip nat pool pool-name[start-ip-addr end-ip-addr

{netmask netmask {prefix-length /} prefix-length} ]

Minimum Access Level: Administrator

Command Mode: config

Defines a pool of addresses for Network Address Translation. Addresses can then be allocated from the pool as needed. Up to 30 NAT pools can be supported.

To remove a pool, use the no ip nat pool command. No NAT pools are configured by default.

Example: ip nat pool Largo 132.53.4.2 132.53.4.250 / 24

pool-name– Name of the pool comprised of 1–20 ASCII printable characters.

start-ip-addr– Starting IP address of the range of addresses in the address pool.

end-ip-addr– Ending IP address of the range of addresses in the address pool.

netmask – Specify a network mask that indicates which address bits belong to the network and subnet fields, and which bits belong to the host field.

netmask – Network mask of the network for the pool addresses.

prefix-lengthor / – Specify the number of bits in a network mask address that are ones and define the network and subnet fields.

prefix-length– The number of bits in a network mask address that are ones. Valid range is 1–32.

[no] ip nat inside source

{list access-list-1-99num pool pool-name [overload] list access-list-1-99num interface intf-type intf-num

[ .sub-intf-num]overload static {static-ip-addr1 static-ip-addr2

protocol static-ip-addr1 static-port-num static-ip-addr2} }

Minimum Access Level: Administrator

Command Mode: config

Allows a user to specify or remove Network Address Translation rules. Both dynamic and static address translations may be specified. Command forms that include an access list are used to specify dynamic translation rules. Packets from addresses that match the access list are translated using addresses allocated from the named pool or the IP address assigned to the interface. No NAT rules are configured by default.

Example: Refer to Chapter 4, Configuration Options.

inside – Inside address translation converts an inside (private) IP address to an outside (public) IP address (and port, if overload is specified for NAPT).

source – Specifies source address translation.

list – Specify the access list number for dynamic address translation. For inside source translation, this access list describes local addresses. If no rules have been created for the specified access list, no translations based on this rule will occur.

access-list-1-99num– A standard IP Access list. The valid range is 1–99.
