nat address-group
Syntax nat address-group group-number start-address end-address
undo nat address-group group-number
View System view
Parameter group-number: Index of an address pool, in the range 0 to 31.
start-address: The beginning IP address in an address pool.
end-address: The ending IP address in an address pool.
Description Use the
nat address-group command to specify an address pool for NAT.
Use the
undo nat address-group command to remove the configuration.
An address pool is a set of continuous IP addresses. When an internal packet is
forwarded to the external network, the system selects an address from the pool to
serve as the source address after address translation. An equal start-address and
end-address means there is only one IP address in the address pool.
Note that:
■ You cannot delete an address pool which has been associated with an ACL.
■ An address pool is not needed in the case of Easy IP where the interface’s
public IP address is used as the translated IP address.
n
■ The volume of an address pool (that is, the number of addresses contained)
varies by device models.
■ For some devices, the addresses in their address pools cannot include the
addresses in the normal address pool, the public IP address of interface in the
case of Easy IP or that of the internal server.
Example # Configure an address pool numbered 1 that contains addresses 202.110.10.10
to 202.110.10.15.
