# It gives you the freedom to do anything you want with it.
# Use the correct name for the tap device:
# The environment variable $INTERFACE is set to the right name
# on most platforms, but if it doesn't work try to set it manually.

# Give it the right ip and netmask. Remember, the subnet of the
# tap device must be larger than that of the individual Subnets
# as defined in the host configuration file!
