I can help you make a game server. Here's a few things we need to check before we make it.
1: Does your router/modem for your connection have NAT (Network Address Translation)? You can find this out by logging into the device and seeing if it supports Port Forwarding as well as Universal Plug-and-Play (UPnP), as well as DMZ. If so, we'll need to do some port forwarding.
2: Do you have a computer that will have enough resources to handle a server?
3: What is your connection speed? Each player connected to the server will take at least 4KB/s (32kbps) of upload bandwidth, and roughly 1KB/s (8kbps) of download bandwidth. Go to
www.speedtest.net or your preferred speed test site and post up the results.
4: Do you have the server files for the game you want to run a server on, or do you know how to set up a listen server/port forward? Or better yet, what game do you want to set up a server with?
Post up the info in this topic and one of us can surely help out.
