Port Forwarding not showing up

Ive seen other people have this problem but they from about a year ago and they didnt have the solution i needed. For the past five days i have been trying to setup a rust server but everytime i try to port forward it says it has port forwarded and when i go to check the server or check if the port is even open it just says theres no open ports for this host ive tried turning off advanced secuirty and firewalls on the router is there anything i can do.
