Must Contiguous Addresses Be Specified in a NAT Address Pool?
The NAT address pool contains an address segment from a specific start address to a specific end address. You can configure address exclusion to exclude special addresses in this address segment. Therefore, the addresses in the NAT address pool can be non-contiguous.
In addition, the start address and end address can be the same. In this case, the NAT address pool contains only one IP address.
