I have an Arris TG862G modem, and an ASUS RT-AC66U router. My goal is to be able to port forward.
The Arris modem was provided by Comcast, and I have that hooked up to connect to the internet. My ASUS router is then connected to that. I found out that this means I technically have two routers on my network. I first tried to port forward on both devices, but this did not work.
Next, I tried changing my Arris modem to bridge mode so that I am only effectively behind one router. I then tried port forwarding on my ASUS router, but my ports are still listed as unopened.
I'm completely out of ideas on why this is happening.
This is what my ASUS router WAN page looks like:
This is the Port Forwarding Page of my ASUS router:
I want to note that I also do have DMZ enabled at the moment, but I have tried turning that off. I am not really sure whether I should have DMZ enabled. To my understanding, DMZ should have allowed for a point of access to my network from a single computer.
Additionally, I also have NAT enabled too.
