ip nat pool

Syntax

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

no ip nat pool name

Release Information

Command introduced before JUNOSe Release 7.1.0.

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.

Options

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
