I'm trying to get a modded Minecraft server up and running to play with friends remotely. I've done this in the past with no issue but I seem to be hitting a roadblock. I've forwarded the appropriate ports, reduced my firewall on the router and the machine that's hosting the server, and even placed the server as a DMZ host. But port 25565 still registers as closed when the server is running. Not sure what else to try before calling up my ISP. Any help is appreciated, thanks.
