I used to run many minecraft servers. I recently moved and have a different cable company (time warner cable) and ever since then my minecraft servers have not been working properly.I tried to fire up the servers after configuring them accordingly but to no avail. I tried everything I know and I start them and they start smoothly and they are running but myself or any other cannot join(yes I have been using a new external ip adress tp try to connect). I try to join the server local host but it doesnt work either the connection refuses. Not sure what more to do so please help! I use and iMac if it helps any and before I moved I had a direct cable from my computer to the router. Since I have moved my comouter is not near my router so im only connected over wifi. Not sure if this changes anything but it does then please! let me know!
