If you use both a modem and a router, then you need to do the following:
1. first on the modem (the box closest to the internet) create rules to forward the above ports to your router;
2. then on the router (the box between the modem and your devices) create rules to forward the above ports to the static IP address for your server.

<span class="glyphicon glyphicon-warning-sign"></span> Some internet service providers block port 25 (mail SMTP) by default to fight spam. Some other ISP don't allow to use port 80/443 (web) freely, though it's less likely. Depending on the ISP, it might be possible to open them in the admin interface...
