Port Forwarding on a D7000 not working

I'm a networking novice: please be patient.
I've looked at several similar threads (19601811517696, 1556128, etc) for this device and other modems/routers and have been unable to resolve my issue. I don't know what information is necessary to provide so if there's something missing below please let me know and I'll add it. 

 

I'm trying to open a handful of ports (80, 8080, 8085, 7878...) using these online steps (Netgear User ManualOpenMyIPPortForward) to host a game server for LAN users and a couple trusted users outside of the network. When using services such as YouGetSignal and CanYouSeeMe the ports are invariably shown as closed. Below is my forwarding configuration within the modem. 
2021-05-28_18h59_08.png
The host computer has been given a static IP (192.168.0.111) which is outside my DHCP range (2-100).

My ISP is Centurylink. They have been unable to resolve the issue (typically just restart computer, reboot modem, revert to factory settings and try again). I had this same issue with a Zyxel modem a few years back and never got it figured out then, either. 


This is a D7000 (v1? serial: 4T7371BL00DC5) with Firmware v1.0.1.78_1.0.1.
The host device is on Windows 10 Pro x64, version 10.0.18.362 build 18362. 

I have opened TCP/UDP ports in the Windows Defender Firewall.
Tried disabling the Windows Firewall entirely, as well as deactivated my device's AV software (non-premium Avast) without luck.
I'm using a dynamic DNS provided by no-ip and have tried disabling that, but not sure if it would have have had any effect.
Turned on/off the UPnP as suggested in another thread, but again don't know enough to know what that changes.


Open to any and all suggestions.
Again--I'm new to this--so links to other resources/threads are welcome in case I'm missing something super obvious.
Thank you all for your time.

   Not the best examples, I'd say.  The D7000v2 has its own problem in
this field (no NAT loopback), so discussions of that model can mislead a
D7000[v1] user.

   Why?  You're running a web server?  And what else?

   I can't (yet) see your picture.  In-line images must be approved
by a moderator before others can see them.  The time required varies.
Attachments have no such limitation.  Of course, attachments have their
own one-per-message limitation.  In the mean time, copy+paste is your
friend.

   You have DSL service?

   A D7000v2 should say "D7000v2" under "Model" on its product label.

 

> [...] with Firmware v1.0.1.78_1.0.1.

 

   That's a D7000[v1] firmware version.

 

   D7000[v1] firmware is far from bug-free, but, so far as I know, its
port forwarding works.  (I currently have about 16 port-forwarding rules
configured on mine.  Which is also running V1.0.1.78_1.0.1, with
(resold) CenturyLink (old. slow) DSL service.)

   Sounds good to me.  It should prevent the router from trying to do
automatically what you're trying to do manually.

Thank you for the response, antinode. 


"> Why? You're running a web server? And what else?"

It's a private game server for an old MMO which includes web-based account creation system. I'm following a guide for that process but am stuck on getting the necessary ports opened, everything else appears to work fine. 


"> I can't (yet) see your picture. "
Sorry, I was unaware of that limitation. I've included an image with a few screenshots together. The port forwarding configuration is obviously marked #1 in the attachment, the other marked bits are mentioned later in this post. Transcribed example:

 #Service NameService TypeExternal Starting PortInternal Starting PortServer IP Address
1W80TCP/UDP80-8080-80192.168.0.111

Very relevant experience then, I'm glad you reached out! Yes, it's DSL service and since the v1 is capable, I'm sure it's user error in some capacity, I just don't know where I would've messed things up. 

 

"> For the usual problems with port forwarding, see: https://community.netgear.com/t5/x/x/m-p/1859106"
I've read through the thread, so here are a couple additional points of information and questions.

  • I don't think I'm using an intermediate NAT router. The D7000 is my only modem/router and the host computer is connected directly to it with ethernet. 
  • The Internet IP Address listed in Advanced>Advanced Home is the same IP that is returned when using WhatIsMyIP
  • I've made sure the system always has the right address using (I think) static configuration and reserving an IP outside the DHCP range. The IPv4 address I see on the host when using /ipconfig and when looking at the list of wired devices in Advanced>Attached Devices shows the IP that I reserved (attached #2).
  • I'm frankly not sure how to "access the server from a system on your LAN using the server's LAN IP address" so I had to search around. Is it just a matter of entering 192.168.0.111:80 (tried with and without the port) in the browser address bar of another computer on the network? When I do this, I receive a message indicating the address refused to connect (attached #3). 


Thank you again.

   Thanks for the helpful link.

   That clears usual problem 1.

 

   The port-forwarding rules look plausible (if you want those ports).

 

> [...] Is it just a matter of entering 192.168.0.111:80 [...]

 

   "http:192.168.0.111", with or without ":80".  A modern browser might
default to "https:192.168.0.111", which implies ":443".

 

> [...] refused to connect [...]


   Welcome to usual problem 3.  "Connection refused" normally means that
you've reached the destination system, but no one there is listening at
the specified port.  And, as it says, "If you can't access the server
locally, then there may be little chance of doing it from the outside
world."

 

   Knowing nothing about your game server, I can't tell you if you're
not running it correctly, or if it's not working for some other reason.
Do the ports other than 80 do anything different?
