Parameter
number: Sequence number of the address pool pair, in the range of 0 to 7.
overlappool-startaddress: Start address of the overlap address pool. Note that no
intersection is allowed between overlap address pools.
temppool-startaddress: Start address of the temporary address pool. Note that no
intersection is allowed between temporary address pools. Temporary addresses
cannot be the existing internal or external addresses, so you are recommended to
choose private network addresses as temporary addresses.
pool-length: Length of the address pool, in decimal format. The associated overlap
and temporary address pools must be configured in the same length, with one
overlap address corresponding to one temporary.
mask: Subnet mask of the address pool.
Description
Use the nat overlapaddress command to configure the mapping entry from an
overlap address pool to a temporary address pool.
Use the undo nat overlapaddress command to remove the mapping
configuration.
n
One overlap address pool corresponds to one temporary address pool. The
conversion rule is as follows:
Temporary address = Start address of the temporary address pool + (overlap
address - start address of the overlap address pool)
