Alice Box AH4021 routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need 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.
The basic process to open a port is:
- Setup a static IP address on either your computer or device that you want to forward a port to.
- Login to your Alice Box AH4021 router.
- Navigate to the port forwarding section.
- Click the Configuration avancee link.
- Click on Serveurs virtuels(NAT).
- Click on Serveurs virtuels.
- Click the Ajouter link.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Alice Box AH4021 router.
It is important to setup a static ip address in the device that you are forwarding a port to. This ensures that your ports will remain open even after your device reboots.

- Another highly recommended way of getting a permanent IP address is to set up a DHCP Reservation.
- Or, follow our Static IP Address Setup guides.
With DHCP reservations you can manage your devices from your router. This centralizes the management of your network and helps prevent IP address conflicts. Using this method you do not have to log in to your devices separately.
Now we are going to login to your Alice Box AH4021 router. Your router has a web interface, so you will login to it using your web browser. This can be either Chrome, Firefox, Internet Explorer, or Edge. It usually does not matter which browser you choose to use.

If you are looking for the ports for a different application you can find it by either:
Enable the Autre Service radio button.
Create a name for this forward and put it in the Autre Service box. The name is only used as a reminder and has no effect on the port forward.
Enter the IP address that you want to forward these ports to in the Adresse IP du poste serveur box. You can enter either the IP address of your computer or the IP address of another computer or device on your network.
If you are forwarding a range of ports then you need to enter the lowest number of the range into the Port exterieur - Debut and Port interne - Debut boxes and the highest number of the range into the Port exterieur - Fin and Port interne - Fin< boxes. If you are only forwarding a single port then you can enter that same port number into the Port exterieur - Debut, Port exterieur - Fin, Port interne - Debut and Port interne - Fin< boxes.
From the Protocole box select the protocol for the ports that you want to forward.
After you are done click the Sauvegarder button.
Your ports should now be open. It is time to test them.
