# Firewall script for ChilliSpot
# A Wireless LAN Access Point Controller
#
# Uses $EXTIF (eth0) as the external interface (Internet or intranet) and
# $INTIF (eth1) as the internal interface (access points).
#
#
# SUMMARY
# * All connections originating from chilli are allowed.
# * Only ssh is allowed in on external interface.
# * Nothing is allowed in on internal interface.
# * Forwarding is allowed to and from the external interface, but disallowed
# to and from the internal interface.
# * NAT is enabled on the external interface.
