80, 443 and a few others. They have them listed on their site but I can't see some others that they don't have listed (ex: 443) when I use canyouseeme with my Cox service.

Tried using Domotz the other day and I could get into the router off-site via Port 80 but when I tried to do a firmware update, I got an error message 20 seconds later or so that said something along the lines of "port blocking...".

We've run into this 2X in a week and have never had issues before so I was wondering if they just started blocking these ports in our area.
