Port forwarding not working. Help?

Hello ive been trying to port forward multiple ports for a game (only one is needed but the others werent working so i tried more) i disabled advanced security disabled my firewall restarted everything. Still the ports are not open despite saying they are on the xfinity website which i used to open the ports. Also on the default admin gateway i tried enabling and disabling port triggering im not sure what that is if anyone could tell me that aswell but i mainly need help solving my port forwarding problem. Thanks. Also I found a couple other users post explaining the exact problem so this isnt just me and helping me would help at least a few other people.
