Guten Abend Matthias!

But if the gateway has only one public IP address with which to map all
privates addresses, this would indeed by n:1 mapping, no?  To support that
for ported protocols (eg TCP/UDP), the port must be remapped to
differentiate traffic.  Is this functionally not equivalent to Linux
"masquerading"?
