ip nat pool

Description: 

Creates an address pool from which the NAT router obtains an address when performing a dynamic translation. You can create address pools with either a single range or multiple, nonoverlapping ranges. The no version removes the NAT pool.

NOTE: The router will not allow you to remove a pool that has allocations outstanding. Before removing this type of pool, you must remove the dynamic translation, clear any outstanding translations, and then remove the pool.

 CAUTION: Specifying a range in "single line" mode from the CLI replaces all other ranges. You cannot specify a range in this mode if any existing ranges are in use. To add additional ranges, issue this command to access IP NAT Pool Configuration mode.



 

Syntax: 

ip nat pool name [ startIpAddress endIpAddress ]
{ netmask networkMask | prefix-length length }

no ip nat pool name

• name—Name of the address pool; 32 alphanumeric characters maximum
• startIpAddress—First IP address (inclusive) in the NAT pool range you are creating; omitting this value in the command (along with endIpAddress) launches the IP NAT Pool Configuration mode, in which you can enter multiple, discontinuous ranges
• endIpAddress—Last IP address (inclusive) in the NAT pool range you are creating; omitting this value in the command (along with startIpAddress) accesses IP NAT Pool Configuration mode, in which you can enter multiple, discontinuous ranges
• ipAddressMask—Subnet mask for any NAT pool ranges you specify
• length—Length of the network prefix; the number of bits masking the base address that results in the address that you want to match
