Thx for replying. I tried everything you wrote w/o any luck

Q1: I believe it's cable. My connection is 100/100 Mbit/s via optical fiber.
Q2: I don't believe i have a modem. I connect my WAN cable to an ethernet jack in my wall.
Q3: See Q2.
Q4: See Q2.
Q5: It says 212.107.157.49
Q6: See Q2.
I'm going to save all my settings to a file and restore my device to factory defaults and see if it works with default settings.
EDIT: Restored my device to factory defaults and went through the quick installation and then forwarded all the ports needed. But it didn't solve the problem

EDIT2: The clock on the router seems to be having problems aswell. Every time i reboot the router it rollbacks x minutes. So the time stamps in the logs are not correct.
EDIT3: Not even DMZ works
