Syntax NAT ADD RESVMAP <name> GLOBALIP <interfacename> <globalip>

[<localportno> [<2ndlocalportno>]]]

Description This command maps an IP address from a global pool (created using the NAT ADD

GLOBALPOOL command) to an individual IP address inside the network. NAT trans-

lates packets between the outside IP address and the individual host based on the trans-

port information (TCP or UDP or both) given in this command.

Note: Before you can add reserved mapping, you must enable a NAT object using the command NAT

ENABLE.

You can define reserved mappings for a range of ports and/or translating port numbers.
