X6 R7900 Port Forwarding Not Working at all
Running into a peculiar problem! Windows 10 PC Switched off Windows Defender and Antivirus - ALL OFF Netgear Router Firmward - V1.0.3.18_10.0.42 NO VPN I am not able to get it to work for ...
Summarizing all the steps on how to resolve this!
1. You should have something listening on the port to check if it is open or closed. If nothing is listening, it will show as closed.
2. If you have a Router and a Wireless Modem, you should either
a. Make Router as a "Transparent Bridge" (Frontier FIOS term) and Port Forward in the Wireless Modem.
b. OR Port Forward in the Router AND Wireless Modem.
3. You should make a hole in your Firewall - Windows Defender in my case - I modified in Advanced Options -> Inbound Rules and Outbound Rules.
The software I used to test
a. Simple TCP Listener but I saw that on higher port numbers you have to quit and restart. Seems like a bug in it.
b. Simple Port Tester - The catch is it will set up a rule in Firewall that this program has all ports opened (and closed) during testing. Thus during testing it will open a port, listen on it, sent the request from its website, if received, report success, port is closed.

There's your problem. Cascading multiple routers can cause multiple
problems, including this one.'

Disabling the wireless radio(s) in the "FIOS Router" does not stop it
from being a router.
> Perhaps, Frontier FIOS router blocks inbound port requests?
Certainly, not "Perhaps". People in the outside world are talking to
that router, so that router is where you'd need to do port forwarding,
except that your server is connected to a different router.
The usual solutions are: 1) Configure the inner router (R7900) as a
wireless access point, or 2) Configure the outer router ("FIOS router")
as a non-router (modem-only, "bridge"). I don't know what your
(unspecified) "FIOS router" is, so I don't know if it offers a good
modem-only mode.

Naturally. It might work from the outside world, too, if your R7900
were connected directly to your ISP, but you have another router in the
way.

Including this one:

Answering that one might have saved everyone some time and effort.
You might want to check that on your (unspecified) "FIOS router",
before doing more work, and then discovering that you have a still
bigger problem.

If you have two _routers_, then you should do something to one of
them so that you have only one router. See "The usual solutions are:
[...]", above.> [...] and Port Forward in the Wireless Modem [...]
Port forwarding should be done in the (one) router (which might be
combined with a modem).
