Port forwarding problems

Question

I am having an issue with port forwarding. I have two laptops running off the same Netgear router (@10.0.0.1) - one at 10.0.0.5 and the other at 10.0.0.12. The apache server on 10.0.0.12 is listening on port 8080. Here is how I have this set up in my router

I can connect directly to the server using http://10.0.0.12:8080/test in a browser and it works fine

But when I try and connect through my router at 10.0.0.1 (http://10.0.0.1:8080/test), I get

what am i doing wrong?

" Other than the sloppy problem description?"&nbsp;Wow....attitude much? Never mind. I'd rather figure it out by myself.

&gt; Wow....attitude much? [...]&nbsp;&nbsp;&nbsp; Wow, childish much?&nbsp; If I had failed to identify my own router, thenI might be a little less indignant about an accurate description of mywork.&nbsp; Or would you describe it differently?&nbsp;&gt; [...] Never mind. I'd rather figure it out by myself.&nbsp;&nbsp;&nbsp; Ok by me.&nbsp; You already have about all the relevant general advice,and my best psychic guess.&nbsp; Until you provide some useful information ofsome kind, you have my best wishes in your future endeavors.

Kind of difficult to help someone who doesn't tell us what hardware they are trying to fix.
&nbsp;
So excuse me for throwing more questions at you.
&nbsp;
What firmware version do you have on the unnamed device? A number is more useful than "the latest". (It may not be by the time people read this.) There can also be newer versions, or "hot fixes", that do not show up if you check for new firmware in the browser interface.It might also help if you told people what the modem is in front of this router, if there is one. The model number could be useful. Is it, by any chance, also a router, with a set of LAN ports on the back?The reason for asking is that a lot of people turn up here trying to put a router behind a modem that is also a router. That can complicate troubleshooting.For example, like others, I am puzzled by the IP address of your router, 10.0.0.1.
Did you set that deliberately? Or did your anonymous router pick that? (That could be a clue to your plight.)
&nbsp;
Apologies for all the questions. But you can help people to help you by providing the information suggested in this forum's header:
&nbsp;
Subject (Include model number and brief summary)Model (Recommended - Helps the community give the best answers)Body (Include additional detail including model version, firmware, OS and environment where relevant.)
They are there for a good reason.
&nbsp;
Apologies if this sounds rude. But you can't expect help if you don't tell people what you are doing and what your network looks like.

I have no problems answering questions and providing more information. The rudeness in the questions is, in my opinion, unnecessary and just goes to try and booster someone else's ego. My old pappy used to tell me there's two ways to build yourself up. First, you can build everyone else up around you and then you will get carried along with the tide. The other way is to tear everyone else around you down. Looks like this forum - or at least some people on it - have chosen the latter path.&nbsp;Here's a secret. My job is a support engineer for a major company. I am continuously amazed at the lack of information I am provided in order to solve an issue. But one thing I DON'T do is denegrate the people that are asking the question. They don't know as much as I do and I don't think it's right for me to expect them to. This is what I do for a living. So, in order to do my job, I ask them for additional information in a polite and civilized manner. That's how to get the job done. Based on this forum, and I'm probably over-reacting a bit, I doubt I'd ever buy another Netgear router again.
