I have a good idea how networking works. Right now with my ISP I have one external static ip. All of my computers/devices have this one external static ip, why isn't there a conflict? I have a Sonicwall at my home as the main router as well, I have opened the port 21 on the sonicwall on a computer with an interal ip 192.168.1.3 (example) so that I can connect to the computer on port 21 externally.
Now, if I wanted to open let's say, port 25 on another computer with the same external ip address, would it work or would there be a conflict then?
Basically, is it possible to keep the static ip address for multiple computers and opening ports with the help of a proxy or dns?
