Setting up a Terraria server. (with out Himachi)

To begin, you'll need to know your Default Gateway. To find this, go to your start menu and open your Command Prompt (You can type cmd into your Windows 7 search bar). Next type in 'ipconfig' as seen below.

After you type in 'ipconfig' a new window will pop up.

(sorry for the crappy editing folks) 

Find where it says "Default Gateway" and type that into your URL bar.

After you enter your Default Gateway into your URL bar you should get A pop-up that looks something like this

Now you might be freaking out right now because you probably have never set any password for anything like this before. Not to worry. Your default username should be admin and your password should be password. Secure right? If you password's not password, check on the bottom of your router and there should be a username and password printed on some sort of sticker.

Once you've successfully entered your username and password, you should be re-directed to your router's webpage, specific to your Default Gateway.

  

Now here's where it get's a little tricky, because the next steps vary from router to router. So, I'll show you how mine is, and if you have any questions, you can always Facebook me  https://www.facebook.com/stopdropandpanic

Next you're going to click on "Default settings" 

Next click on "Virtual Server/ DMZ" (again it varies from server to server)

Click  "Add Virtual Server/ DMZ"

enter your "Default Gateway" in the space provided.

Next type 7777 in both the "Start Port" and the "End Port"

After this you should be ready to play!

Note: When other people are trying to join your server, they DO NOT use your default gateway.
Go to google.com and type in "what's my ip"

Have your friends enter your public IP adress as shown here.
