Ever since the switch from Time Warner to Cincinnati Bell Fioptics, the Raspberry Pi2 and Pi3 that I’ve been using for testbed Linux servers have been out of commission. I’m struggling to come up with a way to bypass the Port 80 block that CB and many ISPs put in place to protect users equipment (that is the theory). About the only option that might work semi-well is to use a different port and services from a company like no-ip.org. Currently the Raspberry Pi 3 is running on port 8080 so it looks as if it might work? (Still looking for self directed options tho)
Port 80 Redirect: This option needs to be used if your ISP blocks port 80 like most commonly do. It enables you to reach your server without having to type the port after the hostname.
Example: Without Port 80 redirect you would have to type in the following into your browser: yourhost.no-ip.org:8080.
