I have an internet connection and I need to share that service among 3 BBBs that are operating on the same site.
At any time, I will need to review (or change) remotely the configuration of each one. To do this, the ISP will assign a public IP to your router. I will connect the 3 BBB to a switch to share the internet service and configure the router with Network address translation (NAT), that is, to each BBB I will assign a different IP address and port. That way when I’m anywhere from the browser (Google chrome or firefox) of my lap top, I will write the public IP and the port assigned to each BBB to access each device.
I know how to assign a static IP to each BBB, but not how to change the default port (3000). Is it possible to program different ports to each BBB?
