gmod server wont go online ( port forwarding error )

[MoustacheSpy]

Hello.

So i installed gmod using the steamcmd correctly and the server is working locally but im having a problem with port forwarding. Below you can see a screenshot of my forwarded ports. I believe that those are the correct ones. When i type in my ip into a online port checker is says that the port 27015 is closed along with all of the other ports i specified. What is happening??? The ip in the local host window is my local ip. I made it static. Im connecting to the internet using my android phone and usb thethering. My internet setup consist of a a1 WLAN BOX/router ( austrian company ) Netgear WN3000RP repeater ( not shure if thats the correct number ) and my phone that i use because my pc doesnt have a wlan module.

Here are the ports:

Translation of the first row of the table from left to right:
Description traffic comes from: external port: internal port: local host active status

also denselben Port means: The same Port.

My server is running on the 27015 port. My friends cant connect using the ip the dedicated server itself gives me + port nor my public ip adress + port. Only i can connect ( because im in the same network )

What am i doing wrong?
