# WANIFACE is the interface from which you connect your PC to the
# BTU.
# If you are using a vlan-tagging switch, set INETVLAN to blank.
# If your PC is connected directly to the BTU, set it to 500.

# As for IPTV, I haven't quite tested it as my netbook has only
# one ethernet NIC ... will try it with a PC one day. You will need
# another NIC to connect to the set top box. Set the NIC (eth1, etc)
# under IPTVIFACE, and set IPTVVLAN to 600. I think.

# don't forget to install the following packages:
#  sudo apt-get install vlan pppoe ppp bridge-utils
