My neighbor recently switch to the panoramic modem by Technicolor. I installed his security cameras. Can't connect outside of the house. I opened the necessary port, but still being blocked. Attempted to turn on DMZ for the DVR, but got error. Turned off Advanced Security. Still blocked. Have reset numerous times. Disabled port forwarding with Advanced Security off. Still blocked. Now I get error when I attempt to add port forwarding. We called Cox. Sign up for $10 monthly plan and someone will help you? Told the girl better option is to send the modem back and get one that we can work with.
If anyone has a solution I'm all ears. Saw on another post were a Cox Contributor said need to call manufacturer for your system since not Cox cameras. Ridiculous! I've set up a lot of DVR systems and never seen an issue like this. I also have Cox internet, but I'm not using this modem and never will.
