R6080 Firewall isn't operating correctly
Recently, I've been having an issue with all my devices, and my R6080 router. A few days ago, I tried to enable a Port Foward. When I found out the packets were still being dropped, I tried to enable...

What, exactly, were all those "all the values needed"? It's nice
that you're happy with what you did, but that non-description conveys
exactly no useful information to the non-psychics in your audience.

The same holds true for your judgement of what "all the values
needed" might be. You might be right, or you might be wrong, but if you
keep everything secret, then we might never learn which.

Swell. So, if I wanted to replicate your problem here, that tells me
to do what, exactly? Also, as stated above, I'm much less interested in
your conclusion than I am in the actual evidence which led you to it.

Swell. So, if I wanted to replicate your problem here, that tells me
to do what, exactly? Also, you can't see "the packets". I don't know
what you actually can see, but I doubt that it's packets. Which part of
"actual" was unclear to you?

Still true.
With my weak psychic powers, I can't see any IP address(es) of any of
your devices, or your port-forwarding rules, or how you tested anything,
or what happened when you did whatever you did.

Did you read any of that, or answer the questions, or perform the
tests? Or am I talking to a wall, here?
If your (unspecified) "an Arris modem" is actually "a Modem + Router
combo", and its router section is active, the you'd need to do any port
forwarding on it, not on a separate R6080 router.
In such a case, most likely, you'd also want to configure the R6080
as a wireless access point, rather than as a full-function router.
Visit http://netgear.com/support , put in your model number, and look
for Documentation. Get the User Manual (at least). Read. Look for
"Use the Router as a WiFi Access Point Only".

You might also want to consider answering some of the many
still-pending questions.
As far as I know, the values are the internal IP of the host, the TCP or UDP service, the external and internal port range, and service name. For tools, as stated above, I used the Command Prompt (ping + telnet) to execute commands to determine the status of a port. I used port fowarding, not triggering. Also, my modem is out-of-date. I can't access a web interface for it, as far as I know. It's an Arris TM822.

Whew. That's a modem, not a modem+router. Should be harmless.

Have you tried "http://192.168.100.1/"? But with a simple modem, I
doubt that it matters.> For the usual problems with port forwarding, see:

> [...] Is there some actual problem which you are trying to solve?
The problem I'm trying to solve is for the packets to arrive at my computer. I have a Netgear R6080 + Arris TM822. When I try to connect to google.com for example, the connection is unable to open. When I use telnet, this shows up. (I used port 1578 as a random port, for this test.) Connecting To www.google.com...Could not open connection to the host, on port 1578: Connect failed. This is the problem.
P.S.: I'm not a computer expert, so some of the imformation is difficult to interpret. Please bare with me.> The problem I'm trying to solve is for the packets to arrive at my

"this"? "When [you] use telnet" _how_, _what_ "shows up"?
See "As usual, [...]" above.

I don't know what "This" is.

I'd already guessed that.
The less you know, the more important accurate, detailed, precise
descriptions become. What you see, what you did, and what happened when
you did it, are what matter. Non-descriptions like "unable" (or anything
involving "packets") often convey little or no useful information. (In
this case, "no".)After not getting a straight answer to the most basic questions,
repeatedly, I'm worn out. Perhaps someone else has more time to waste
this way than I.
