Now one of the biggest issue people have when going to play online is that there are little to no games being hosted. Then when you go to host, because by some off chance there are people waiting for a game, no one can join you. They all get disconnected and "drop from server". This can easily be fix. the Monk has come out this a small booklet that helps you fix the issue and that issue is your router.
Unfortunately, public routers are not as nice as the privet sector. This can lead to the public having issues with being able to use certain features of their computer and software. the Monk has overcome that issue to help us out with that so that we can host games and have fun with one of the biggest RTS games Sins of a Solar Empire.
This is the link you will want to go to, http://themonk.ca/Monk/Networking_and_Sins_by_the_Monk.pdf. Follow everything that the Monk has laid out and you will be hosting games. Now I did have to alter one thing from what the Monk did but, it was very minor. Instead of 192.168.0.1, I did 192.168.1.1 to get access to my router. Now if you get stuck just use the forum. There is always someone who knows something that can help you out. Gl Hf and hope to see you out there.
