Night Hawk R8000 Open ports -I DONT KNOW WHERE TO START or Begin!
I'm going to try not to rant too much. My apologies if i do. I have XFINITY internet svcs, I have a Netgear Modem CM1000, and a NIGHTHAWK router R8000. I attend a local college, Univ. of Houston D...

I have no idea what that means to you. To me, "completed the task"
means success. With my weak psychic powers, I can't see what session

That's swell, but no one provided them to _me_, so I can't see them
any better than I can see what you're doing.
From here, Telnet to "gator.uhd.edu" (216.145.162.35) returns
"Connection refused", which suggests that it's not listening on port 23.
Which is entirely reasonable. It does seem to be listening on port 22
(SSH), but I lack any valid credentials there, so all that I can do is

"15.72.90.6"??? That's a _public_ IP address (belonging to HP[E]).
You should not be using it (or anything like it) on your LAN.https://whois.arin.net/rest/net/NET-15-0-0-0-1/pft?s=15.72.90.6
Again, I'd suggest a settings reset on your router. And, this time,
when you're configuring it after that, leave the LAN subnet at its
default ("192.168.1.*"). And don't play with any settings which deal
with incoming connections.Curiosity compels me to ask how you decided that "15.72.90.*" was a
reasonable choice for your LAN subnet.

Ok. Should be easy enough. Did they provide instructions?

You lost me. What, exactly, does "tried TELNET" mean to you? Telnet
and SSH are two different services.
"tried" is not a useful problem description. It does not say what
you did. It does not say what happened when you did it. As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations. Copy+paste is your friend.

Your (unspecified) "my laptop" runs some version of Windows?
You're trying to make an outgoing connection (as a client) to a
remote SSH server. You should not need to do anything with any DMZ, or
port forwarding, or port triggering, or any such thing, to enable an
outgoing connection. All those features exist to accommodate _incoming_
connections (to your server, on your LAN, which you don't have).
> [...] Returned everything back [...]
"everything"? Did you undo all those misguided setting changes
involving DMZ and/or port forwarding/triggering? If you've lost track,
then a full settings reset might be a reasonable step.

I have no actual experience with either device, but if your general
Internet access (web browsing, e-mail, et c.) works, then I wouldn't bet
on these devices causing your problem. (At least, not until you started
fiddling with the router.)
Okay Let me try to be a bit more precise. I will also atttempt to make some screenshots. I completed the task to ssh into the box. yes they did provide instructions on how to do so. And yes i did follow them. And no, I WAS NOT SUCCESSFUL. I followed the steps for TELNET, then i followed the steps for SSH.( FIGURES 1 & 2). The connection was never successful. I also tried to sftp into the box with a program called WNSCP, and even that connection was unsuccesful.(figures 3 & 4)
Figures 5 - 11 shows you the current setting on my router. My laptop ends with x.x.x.6. I tried to clear logs just to see if maybe it would throw out an error in there when trying to connect. As i said, i undid the DMZ nonsense, but kept the port forward settings.
Figures 10 and 11 shows you nothing in logs while trying to connect.
I am currectly running Windows 10 i5 processor 16gb ram on a HP Elitebook 840 G4

Thanks
I wish you wouldve just said that though.. Something tells me you already knew this was the problem..
Thanks
