I have set a static ip addres, even though someone told me my provider only operates with pseudo static ip (Not sure if this is what prevents the forwarding), after that I changed the setting of my router and tried to check if the forwarding succeded but the port checker says the port is not open or not reachable. This is the first time I have done anything like this, so I could have easily messed up somewhere, but i've read a lot about this and I think i got it right.

I pressed the button on the back of the router in order to reset it but nothing seems to have changed.

My router is a cbv383z2 castle net.
