Creating a Port Forward in Your Router for SpaceChem

SpaceChem is Zachtronics's Puzzle and Simulation game with a release date in 2011.

SpaceChem has the following genres of gameplay.

  • Puzzle games require players to solve a variety of puzzles ranging from logic to patterns to words and numbers. They are sometimes timed and sometimes do not have a time limit. Some puzzle games have a level progression built in to them and others are more in the arcade style.
  • Simulation is a huge category of games that includes driving and flying simulators, social simulations, medical simulations, sports simulations, and even dating simulations. They attempt to mimic the real world in a way that is either educational or rewarding or both. Popular examples include SimCity, FlightGear, and Madden NFL.

Port Forward SpaceChem

When you are playing SpaceChem you might need to forward some ports in your router. Forwarding ports is a useful trick in gaming because it can really help to make your network connection most stable and intermittently even faster. Routers were not designed to allow incoming network requests and some games can play tremendously better if an incoming connection is forwarded through the router to the game.

Before You Forward a Port

Before you can forward a port you need to know the following things:

  • Your router's IP address.
  • The IP address of the device that the game will play on: either your computer or your console.
  • A list of TCP and UDP ports to forward.

How to locate your router's IP Address

The easiest way to locate your router's IP address is to run our free Router Detector utility. It's a part of the Network Utilities suite of tools and it's completely free to use.

How To Forward Ports

To easily and quickly get your ports forwarded use the Network Utilities software. Network Utilities allows you to forward ports only when you need them, and then close them again when you are done. This makes keeping your network more secure much easier. You can also do it by hand.

The general process for forwarding a port is:

  • Login to your router.
  • Find your routers port forwarding section.
  • Put the IP address of your computer or gaming console in the applicable box in your router.
  • Put the TCP and UDP ports for your game in the corresponding boxes in your router.
  • Frequently you have to reboot your router for the changes to take effect.
