Ok, so I've had a bukkit server now for about 3 months. It was working great with a Netgear Router. Around 2 weeks ago, I changed my router to a Motorola. I noticed now that there's a internal and external Port Forward. It was working good until a week ago. My NAT Type changed to moderate and my friends can't join my server. I have a Static IP and correct info everywhere. When I type in local host, it would let me in. If you want I'll post the picture of the Port forwarding. It might be a Firewall problem too... I really don't know.
