# miniupnpd integration for firewall3

# Note: Correct way to do this would be probably to use
# /lib/functions/network.sh, and use network_find_wan{,6}, and then
# network_get_device, then determine their zones using fw3 -q network
# etc. However, network_find_wan* return only one device, and
# frequently incorrect one if multiple ISPs are in use. So this
# current ugly solution works, although perhaps makes holes where it
# shouldn't (if so, do override it in e.g. firewall.user)
