Hi. I used to run a minecraft SMP server on my laptop. Everything was fine: I set up port forwarding, downloaded the software, and it all worked out. I used both bukkit and the standard server for snapshots. The problem is, my server won't show up anymore. My IP Address changed (I think due to some sort of 3G booster that Sprint installed into my house), and now my server won't load on the new (and old) IP. I know the software to run the server works; using the address "localhost" proves this. But the server won't serve its purpose, to be able to play anywhere else. Some help, please? I tried redoing the port forwarding, and that didn't help. I've redownloaded the server software (even though I know that's not it) but still nothing works. I can log on to other servers, just not host one of my own. Help, please, and thanks.
I redid my port forwarding, with the application name being Minecraft with the external and internal ports being "25565". Protocol: Both, "to IP Address" has the address in "192.168.1.102". Obviously the "on" box is checked. I redid this several times. Still won't work.
Try redoing the port forwarding. And if that does not solve your problem then let us know. and we will be glad to look at this with you further.
