I can't seem to be able to get people to connect to my CentrED server. I am using port 6767, I opened the port on my router, but still nothing. I can connect to my project just fine, and so can people on my local network.
Am I missing a step?
Opening the port on your router is not necessarily the same as "forwarding" the port. Forwarding means, that your router knows, to which IP inside your network it should redirect the requests on that port. Open would only mean, that it accepts connections to that port. Since the cedserver is not running on the router itself (probably ;-)), that would fail for outsiders.
