Nothing like that. I was using port 80 I had a web server on a small desktop connected to a weather station and it generated a nice little web page with graphs stats and current conditions.
Upgraded from 3G to 4G then one day I wanted to look at conditions while I was away and nothing. Tried pinging my web address via dyndns and it would not respond... tried a port scan and nothing. Thinking it was a configuration issue or something broke with the apachie server I just gave up was not super important.
Bought a pan Tilt security camera installed it works great inside the home network, tried getting to it from outside the network and nothing! Did some reading on the web and it looked as if all incoming ports are blocked on LTE.. but I see some hams doing stuff wirelessly thru their modems. Wondering if there is a way around it, I also tried the DMZ feature of the modem and nothing.
Yes possibly have to pay for a static address/business account I hope not. I guess I can call but just wondering if there is a work around prior to me considering paying a premium on my already expensive phone bill.
I have no idea if this will work for you but let me describe how I have done it. I have a fleet of raspberry pi's spread across the nation. Most of the ones that are actually mine are within about 10 miles of home. The recent versions of the pi software come with RealVNC installed. What I have now done is to enable cloud connectivity through RealVNC. On a pi with that enabled, I can pick it up and move it to a totally new location, plug ethernet in and have remote access immediately, no configuration to do. I am pretty sure that I have done it through the hot spot on my iPhone which is LTE through ATT. Once into the remote unit through RVNC then you can do anything on that remote network that you can do from a computer at that network. For example, I can log into the remote unit, open a web browser, log into the network router at that remote location and make changes.
You wouldn't need to use a pi for this. RealVNC (home) for personal use is free and you could install it on one of your computers at home. Connect into that computer and it is just like you are sitting at that computer.
Again, no guarantees that this will solve your VZW LTE issue but it might be worth a try.
