How to open a port on the Sagem Fast 2504

Sagem Fast 2504 routers include a very basic firewall that helps protect your home network from unwanted access from the Internet. Since the firewall blocks incoming connections you may need to open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the Internet to your home network.

In this guide we will walk you through each of the steps involved in creating a port forward for the Sagem Fast 2504 router. These steps include how to:

  • setup a static IP address on the device you plan on forwarding these ports to.
  • login to the Sagem Fast 2504 router web interface.
  • find the port forwarding page in the router's web interface.
  • setup a port forward for the online game or program of your choice.

We think that forwarding a port should be easy. That's why we created Network Utilities. Our software does everything that you need to forward a port.
