Before we can forward ports for BYOND, we need to set the port that BYOND will be hosting on. Here is a brief walkthrough on how to do that. Go ahead and open up Dream Seeker.
Load the game that you want to host. Once the game is loaded the Host button in the lower right of your screen shot light up. Click that button and you should see the screen above. Enter the port you want to host on into the Port box. It doesn't really matter what port you choose, but remember it because it is the port you will need to forward. Please enter the port you chose into the box below.
Open a web browser like internet explorer or Netscape. Enter the ip address of your router in the address bar of your browser. In the picture above the address bar has http://www.google.com in it. Just replace all of that with the ip address of your router. By default the ip address should be set to 172.16.0.1.
Click the Application Support button near the top of the page.
Click the Enable Application Support link near the top of the page.
Click the Add a new user-defined application link near the bottom of the page.
We will list a series of lines here that will show you exactly how to forward the ports you need to forward. BYOND Dream Seeker Host requires you to forward the ports you entered above. Go ahead and enter the settings shown above into the Edit Application menu and then click Add Definition.
You should see another page of settings that need to be entered into one of the blank lines on your routers Edit Application page. Go ahead and enter those settings and then click Add Definition.
When you are finished, click the Done button at the bottom of your screen. And that is it! You are done!
