Have you manually set the DNS servers on your router? The router is configured to resolve IPs using 192.168.0.1; that doesn't seem right. [*]

Is 192.168.0.1 the IP of your modem, or some other device you own? (note I'm not asking about 192.168.1.1, that's your router)


[*] As a side note, it's actually possible for your ISP could be using a private IP for their DNS server, but that would be unusual. Also, that IP in particular would certainly conflict with most home routers (but not yours, since it's configured to use 192.168.1.1).

Ok so that's explained, assuming your modem does DNS forwarding (which it probably does, if it's a modem/router).

What symptoms exactly are you experiencing?

Let's test your DNS resolution. These commands try to resolve the IP of example.net, first using the DNS server that's configured on your computer (your modem) and then using 208.67.220.220 instead. This is the IP address of a free DNS resolver server, provided by OpenDNS.
Code:
nslookup -d2 example.net

Code:
nslookup -d2 example.net 208.67.220.220

Please run these commands and copy/paste all their output here.

Ok, I'm seeing expected behavior here... You did manage to resolve example.net to the correct IP addresses (192.0.32.10 and 2620:0:2d0:200::10). The only thing that's not entirely as it could be is the search domain, which is set to domain_not_set.invalid. But assuming this is just a home network, you most likely don't have anything meaningful to use as the search domain anyway -- unless you happen to own your own domain (e.g., dunphy.com) and want to use that as your default suffix for resolving names.

Again, what are your symptoms exactly? What problem(s) are you experiencing, and how did you determine that they were related to DNS? I'm not seeing anything wrong here...

I take it you are running a gaming server on your PC, and you want to set port forwarding on the router to let traffic in, correct?

What errors are you receiving? What indications, if any, do you have as to where the problem might be? What steps, if any, have you already taken to try and narrow things down? Is the complaint coming from someone on the Internet who can't connect? Or is the server not showing up on a server list, or...?

Please try to be detailed; having to play 20 questions makes it harder to help you.

Well the only error I'm getting is this Domainnotsetinvalid one. I thought the Problem was DNS related but I'm not so sure I'm not all that good with routers at all so it's hard for me to inform you of this, problem. And If it helps I have a speed stream 5100 for a modem and a linksys for a router.

The domain_not_set.invalid is normal; it's basically just a default value for your home domain name (it's normal for you to not have a home domain, so the router just sets it to that).

You need to read what I am asking you. I need to know exactly what it is that you want to do, and exactly what happens when you try to do it. Especially if you're not sure where the problem is, it's even more important that you be specific.

If you just tell me "it doesn't work" that doesn't help much. What doesn't work? How does it not work? What did you want it to do? What is it not doing? You don't need to give me technical details that you don't know of; you just need to tell me what you're talking about. I'm not there next to you to guess all this...

Surely you wouldn't call a doctor on the phone and just tell him "it makes noise". You would say something useful, like "my left shoulder makes loud snapping noises when I try to raise my arm above my head".

Tell me the story from the start. Something like "I want to host a Counter Strike server, on my home PC, and I forward port 12345 on my router but when people try to join the game it says connection timed out". Or "gaming site X says I'm not online". But please, be detailed in what you want and what you've tried to do.
