1. Go to
2. Download the 1.6.4 Recommended installer if your using 1.6.4. If your using 1.7.2, download the 1.7.2 recommended installer.
3. Once downloaded, open it by double clicking it (or right-click it and Open With -> Java).
4. Click install server and select your server folder
5. In the folder rename the Forge-__.__.___.jar to forge.jar
6. Make a new Text file and rename it start.bat (remove .txt)
7. In that file type:
java -Xmx1024M -Xms1024M -jar forge.jar nogui
(Adjust the 1024M part for how much memory you want to allocate to the server, 2GB of memory would be -Xmx2G -Xms2G)
8. Run the start.bat file
9. To connect in game use the ip of your computer (localhost if it is on the same computer you play Minecraft on.). You need to port forward for others to connect to the server.
For others to connect, they need to have the same version of Forge. They are required to have the same mods that are on the server, BUT they can have other mods that the server doesn't have, they just won't be able to use what is in the other mod they have.
