So, here's my situation. My ISP provides me multiple ip addresses, if I want them. I want to take advantage of that in a way I think is appropriate. It would be easy if I just used the external, routable ip addresses directly--one for each machine perhaps. But, I want to keep my internal, nonroutable scheme intact. For one thing, I have more machines than routable addresses. For another thing, I'd like the freedom to use the routables by function, rather than specific machine, meaning that I might migrate internally from one machine to another at some point, without changing the externals. So, how do I do that NAT? Let's say I have four IP addresses. They're discontinguous. Internally, I have seven or eight machines (depending on the day). Here's what I know I can do. I can route traffic arriving on address A port 80 to machine A-Prime port 80, and route traffic arriving on address B port 80 to machine B-Prime. But, can I route traffic arriving on address C, whatever port, to machine C-Prime? Without specifying all the particular ports one at a time? Or as some kind of gargantuan range like 1-32767?
