Define four LAN ports on a Belgacom b-box
By default, the Belgacom b-box is configured for two PCs ports and two TV (decoder) ports (see lay-out). However, the LAN ports can be redefined. You can follow these steps on a b-box:
1) Logon to the b-box
The default adress of the Access Point is http://192.168.1.1 (factory setting).
Before changing any of the b-box settings, make a backup (Maintenance, Configuration).
In case of a b-box2 follow the steps in this post.
2) Go to Advanced Settings and select Home Networking
3) Change the VLAN Bindings from IDTV to Default.
4) Save your settings
All four ports are now configured for standard LAN connections.
