People can't connect to my server. (Explicit)

Hello, I'm a proud user of bukkit and I experience a very very uncommon problem.
So I've created my server , everything runs perfectly , I have 1 server , a workstation and a PC all connected on a ASUS RT-N12LX (Router).
The first time I configure it , it ran amazing , The workstation could connect and so did the PC , but nobody else , only the PCs connected to the router.I've powered down the firewall router and the firewall from the server , i've made the ip static , i've portforwaded 1-35000 (on the router and on the PC).Then something strange happended , the PC couldn't connect to the server , only the workstation could , I've asked my self why? (Before I had the server , the minecraft server was on the workstation then i've moved it to the server) so the workstation ip was static and the exceptions for the 25565 port were enabled to the firewall so i've done the same things to the PC, no luck.I've tried to reboot the router , added DMZ for the ip from de server , nothing.Then , the next day (the server hasn't been stoped neither the PC and the workstation) i've tried with the very few luck to connect to the minecraft server from the PC and it worked ( :| ).I was shocked but happy , i've played for a few hours , then i've closed the game and when i've entered again , it couldn't connect (...).
I really don't know what to do anymore, and I don't know why anybody else can't connect that aren't connected to the router..
I think the last chance (only if you guys help) is to go to my ISP provider's company and make 8 static IPs and more bandwidth.

You can see how biilionx was logged on the server , disconnected and then when he tried again to connect , he couldn't connect, I really don't understand.

Static ip
TCP check
UDP check

You can see that everything is working fine , please I would like you to be very explicit in your replyes.

Regards,
cblt.

go into your server.properties file, and change online-mode to true

 

Now it tells me from the workstation and the Pc "Failed to login: Bad Login"

 

It will not log you in correctly, if you're not logged in in your client. If it doesn't successfully log you in, on your client, it will not work.

 

Well yeah I know , but not everyone has an account , and I would really like to have it in offline mode , and just put some plugings.. a lot of people have offline servers..

So any advice besides the online mode? :-??

if you have cracked minecraft you must have online-mode to false otherwise it go's trough the secruity from minecraft.net so it can see that you bought the game if not you get a bad login

 

Buy the game. We don't support piracy here.
