Description
Configure deterministic NAT to ensure that the original internal source IPv4 or IPv6 address and port always map to the same post-NAT IPv4 address and block of ports. In addition, the reverse mapping of a given translated external IPv4 address and port are always mapped to the same internal IP address.
This eliminates the need for address translation logging.
Options
| block-size block-size | The number of ports in the port block.
|
| host address address | The first usable pre-NAT subscriber address, which is used to perform the deterministic NAT mapping. |
| include-boundary-addresses | Include the translation of the lowest and highest IPv4 addresses (the network and broadcast addresses) in the source address range of a NAT rule. This does not apply to IPv6 source addresses. |
