Port Forwarding/DMZ Not Working

[akh023]

I have been trying to open a few ports on my router, and I spoke with a technician on the phone who was AMAZING and tried everything he could do to fix it and then decided to send me a new router. I have since hooked up that router and it still does not work. 

By "does not work" I mean the following:

I follow all steps to enable DMZ or add a port forward, and it creates it and shows in the xFi dashboard. But I go to check if the ports are actually open and they are closed. My router tells me they are all set up, but in fact, they do not work. 

My router model number - tg1682g

Try disabling the Xfi Advanced Security feature as a work-around for now and see. It's buggy ! And there is currently no way for an end-user to be able to whitelist anything;

I have already had that disabled.
