Hopefully, the people that could use this find this. I know there's loads of tutorials for this, and a quick google will return hundreds of walkthroughs for this, but I figured I would make a all-in-one post.

First off, a few things I want to get out of the way:
  • I will NOT be held responsible for anything you do to your network or anyone elses. In using my walkthrough, you agree to that, and claim all fault as your own.
  • Second, a tip: DO NOT give your IP to ANYONE you do not personally know with the intent of having them portforward for you. Letting anyone into your equipment that is not your ISP (internet service provide), PC/internet technician, or close family friend is a massive breach of your internet security. So don't do it.
  • Third tip: don't try and do this on a laptop unless it's a home-only laptop, or you are fully aware how to change static IP's around on the go. I will get into static IP's later, if you don't know what they are.
  • And final: if you have a question, please ask on here, DO NOT private message me. If you'r asking in, someone else might, and this will allow everyone to get the answer. But please bare in mind, I will not provide server support outside portforwarding and linux machines.

Alright, with that out of the way, onto brass tacks. In this I will assist on portforwarding, along with a basic understanding of static IP's, and a small explanion of what this all means.

What does it all mean?

Portforwarding is the process of forwarding info from an internet port to a certain device on an internal network. In other words, its how people connecting to your server connect to your computer on your home network. This is vital, as without this, anyone trying to connect will get stuck at your router as the router has no idea where to send the data it's randomly getting.
Going off of that, in order to make sure the data gets to the right computer, that computer needs to have a static IP. Almost all router use whats called DHCP, which means the devices connected to it can get a new IP anywhere from every 30 minutes to every few hours, depending on settings. To make sure that the port forwarding also gets to the right machine, that machine needs a static IP. This is the first thing you need to do before port forwarding. If you don't have a static IP, people will only be able to connect for no more then 24 hours.

So a static IP...

As I said above, a static IP is the first part of successful port forward.
Before setting up the static on your PC, you will want to reserve the IP for your machine, if your router requires this. Now, this is sadly something I can not assist with. If you are not sure how to do this, or if it's needed, consult the manufacturer your router and/or the manual. Google is also a good place to check, if you have the model of router handy.
Since there are three major OS (Operating systems) that people use, there are three different way to do it. I've provide below a list of how-to's for Linux, MAC, and Windows. On that list will be others, but they are not needed. Again, I will only be able to help with Linux or windows 7 for this, if help is absolutely needed.
This section is something you may want to read over a few times, as you may need to juggle information between your computer and your.


This is the bread and butter of this whole post: as stated a few times above, you should have a static IP on the computer you are trying to use for your server. You should also have that static IP handy, as this is where you will need it.
What you will now need to do if interface with your router and program it so and data coming in on a certain port (for Minecraft, it defaults to 25565) is sent to the server computer you are using. Since there are literally thousands of routers, I can't really do a "one size fits all" sort of thing for this. However, I will be providing a link to a site that has just about ever router ever made listed, and step-by-step walkthroughs on how to interface with them and set up the portforward. All you need is the make and model of your modem.
  1. Click here
  2. Findyour brand of router in the list
  3. Find your model of router in the list
  4. Follow the steps!

Hopefully, I helped more then I confused people. If you have questions, feel free to ask, but again, ONLY about portforwarding! Also keep in mind I will only be able to provide system specific help for Windows 7 and Linux.

Sorry to say this,

All you have to do is login, put your port + IP there and it is Finished,

It varies from PC, OS, network setup, and router. For some (myself included) it was that easy. But for others, its not.
