To setup port forwarding on the Alice Box AH4021 router your device needs to have a static IP address. You should complete one of the following steps first:
Now that you have setup a Static IP Address on your device, please enter the IP address that you assigned to your device here:
Now we need to know your routers IP address. You can find it a variety of ways.
It's ok if you don't know your Alice Box AH4021 router's internal IP address. You can find it by doing one of the following:
Open a web browser like Internet Explorer or Firefox. Enter the internal IP address of your router in the address bar of your browser.
In the picture above the address bar has http://www.google.com in it. Just replace all of that with the internal IP address of your Alice Box AH4021 router. By default the IP address should be set to 192.168.1.1.
We do not currently know the default username and password for your router. If you know them, please use our Comments page to let us know what they are. Thanks!Please visit our Default Router Passwords page if the username and password shown above do not work for you.
If you are having trouble with this guide, then perhaps PFConfig may be your solution. PFConfig is a software tool that will automatically forward ports for your Alice Box AH4021 router to save you time and hassle.
BitComet chooses a random port to listen on when you install it. Before we can forward ports for BitComet, we need to find out what port BitComet is using. Go ahead and open BitComet.
In the menu at the top of your screen, click Options. Clicking Options will cause a menu to drop down. In this new menu click Preferences.
In the menu on the left the top option Connection should be selected. On the right hand side of this window you should see a Listen Port option. That is the port that you need to forward. You can change it if you like. Please enter the listen port below.
There is one more thing we need to do. We need to shut off the UPNP of BitComet.
In the menu on the left hand side under Advanced, click Connection. There should be an Enable UPnP Port Mapping(XP only) checkbox on the right hand side. Make sure it is unchecked.
Now that you are logged in to your Alice Box AH4021 router you should see the following:
Click the Configuration avancee link near the left of the page.
You should now see a new menu. In this new menu, click Serveurs virtuels(NAT).
You should now see a new menu. In this new menu, click Serveurs virtuels.
Click the Ajouter link near the top of the page.
We will list a series of lines here that will show you exactly how to forward the ports you need to forward. BitComet requires you to forward the ports you entered above. Go ahead and enter the settings shown above into the NAT menu.
|Adresse IP du poste serveur:|
|Port exterieur - Debut||Port exterieur - Fin||Protocole||Port interne - Debut||Port interne - Fin|
And that is it! You are done!
Now that you have forwarded ports for BitComet on the Alice Box AH4021 you should test to see if your ports are forwarded correctly.
