    This is a set up that has been working fine for a year now.

    I even had to buy an extra router to be able to host remotely on more than one computer for students playing from home.

    This problem was something that came up suddenly after Saturday afternoon sometime.

    I couldn't tell if it was something going wonky with our Internet, security software, Minecraft, Windows, or what.  There seemed to have been an update to minecraft EE in there to confuse me even more.

    Solution at this time seems to have been...

    create a DMZ (demilitarized zone) on the xfinity router, for any device I want to be able to let outsiders connect to.  Apparently just port forwarding is no longer enough anymore.  And I have not been able to figure out any way to just whitelist all the necessary URLs with the xfinity router.

    Here is a link back to the other thread since it is basically a duplicate

    Update to that old post.  I did finally find the source of the problem, apparently my ISP's router decided to change the way it handles port forwarding and changed the supposedly "static" IP address of device I had all the port forwarding set up for.  Even when I fixed the problem and reset all the port forwards to the new "static" IP address, it still didn't work until I changed it to a demilitarized zone.

    Go figure a month or so later, they changed things again.
