My port is closed, no matter what I do?

I have tried everything. I port-forwarded correctly, I'm sure of that. (see image) I have tried DMZ, I have even shut my Windows firewall and my Arris firewalls down completely, but no matter what I do, my port stays closed. I'm trying to forward port 25565 for a Minecraft server, and it isn't the server. At canyouseeme.org and other similar port checkers, the result is connection refused. I have tried everything I can think of, but for some reason my port is still closed. It isn't just this port either, I have tried other ports to see if they would work, but the result is always "Connection refused."

Added (1). I have tried opening a command prompt and typing 'ipconfig'. I typed in the address to my "Private IP Address" section, but it said Error: Invalid IP address. Invalid network address.

Added (2). My port is closed, no matter what I do
I tried more of these numbers, as well as my public IP, in the Private IP section, but the message came up the same.

Added (3). I found this for my NETGEAR router on the IP shown at the link above: //postimgs.org/apple-touch-icon.png

Minecraft Factions Base Defense

Someone keeps tp glitching into my minecraft factions base and I'm not sure how to stop them. I have a 2 layer think empty buffer layer at the top and bottom of my base, and outside my base we have a sand wall going from bedrock to skylimit. Inside that parameter of sand, our actual base is covered in water. This is what our walls look like from a birds-eye view.

water-sand-water-clay- base interior

At this point I'm completely clueless as to how they are still getting in, it seems like they're just getting through my buffer layers or just tp'ing throw 4 layers of wall?

Does anyone have more experience with defending bases from tp glitches?

I have a minecraft server running through Hamachi. I play with my friends from time to time and recently we just started a new world that spawned us to a Jungle Biome. Ever since the whole game is laggy. Everytime i would break a block it would stay for 10 seconds then finally break.
