Port Closed on 25565

When i startup my server and join via the internal IP, everything is fine.
When i try to join it on the external IP, it doesn't work.
I did some reasearch and found out that if i go to a port forwarding tester,
my 25565 port is closed.
I've checked everything but nothing seems to work.
Can someone please help me?

 

Sorry, this didn't work

 

Then your ISP is stopping you from doing it. Or you just did something wrong.

 

My ISP?

 

Internet Service Provider

if it's possible to port forward your router, it's model type will be here with directions on how to Port Forward

 

My router is a Cisco Linksys WRT160Nv2

 

Then google:
How to port forward on a Cisco Linksys WRT160Nv2

 

First make sure if the router is the problem. To test that you can enable DMZ on it but be aware it's opening all ports and it's not safe. So enable for a short period of time, test to see if port has open so you will know for sure your router is blocking that port. After make sure to disable back DMZ...

 

Sorry for being n00by, but how do i open DMZ?

 

Try to google your router model followed by "enable DMZ"

 

Thnx, but i enabled my DMZ and it still isn't working

 

Does anyone have more suggestions?

 

HELLO?

 

Yeah make sure your firewall for your router is low or off so it can be pinged and ports are allowed through.
