Uh. Why are you trying to connect to a 1.7.2 server with a 1.7.5 client? Those two numbers have to match. – aman207 Mar 1 '14 at 17:55
@aman207 not true, works fine with 1.7.5 client. – Mark Allison Mar 1 '14 at 20:33
I would recommand running the MC server on port 25565 instead of your current one, 25570. That way players don't need to add a port to your server address when they connect. – Frithjof Mar 2 '14 at 18:08
@Frithjof I already have another MC server on that port. :) – Mark Allison Mar 3 '14 at 7:55

If you haven't checked already, make sure you have an exception for port 25570 in your iptables for internal connections. Not sure if this is something that could affect it, but it's worth looking into.

That was exactly it, I had forgotten to add the rule. Thanks! – Mark Allison Mar 1 '14 at 20:28
