Original Source Subnet (Required): Enter the subnet, using IP/CIDR notation that will be masqueraded out of a spe‐

vate’ Internet addresses.
One‐to‐One NAT will perform a complete forwarding of app ports on the Original Destination IP to a new IP address
entered in New Destination. Because the Original Destination need not be configured on this router, an interface is not

One‐to‐One NAT Range will perform the same operation as a single One‐to‐One rule, but over a range of matched IP
