I cant open my port for a Minecraft server.?

[Alex]

Follow the instructions on the page I linked to in my source to the letter.

Are you sure you got your ip from the right place?

In the included picture I highlighted where you should be getting your ip from. go to start, click run and type cmd to get to this prompt. type "ipconfig /all" without the quotes and find the line I highlighted. Your numbers will be different, but it will be in the same place. Also, I am assuming you have Windows. The link given provides how to get your ip if you have Mac or Linux.

Make sure you leave the server IP field empty in the server properties.

Finally for people to connect to your server, they must use your external ip, which can be found at http://www.ipchicken.com/

Also be sure to configure the server following the instructions in the second link in the sources.

UPDATE:
Do you have a firewall?(Even Windows Firewall)

UPDATE 2:
Allow incoming traffic on port 25565 in your firewall as well.

UPDATE 3:
What firewall are you using? Windows Firewall?

UPDATE 4:
Follow these instructions to allow Minecraft port through Windows Firewall:

- Go to Control Panel>System and Security>Windows Firewall.
- Click on "Advanced Settings", then click on "Inbound Rules" on the left hand side and select "New Rule".

- Select Port and click next.
- Leave the selection as TCP, and for Specific local ports, type in 25565; click Next.
- Leave the option as Allow the connection.
- For profile, select all options and click Next.
- Name it and click Finish.
