Can't port forward belkin router?

I'm making a minecraft server I need to port forward I already disabled firewall well I click the apply changes button nothing happens

Some isps will not allow servers on any port especially not 80, on belkin routers (not very good routers) it's easier to edit a preset than set one up from scratch

Post model # of belkin router.

Ensure firewall on PC && broadband modem (make/model #?) [IF separate of router]. Are open for game.
