Wireless Networks Made Easy (cont'd)

Either $int_if is your wireless interface, or in /etc/pf.conf, add:

air_if = "ath0"

and

match out on $ext_if from $air_if:network nat-to ($ext_if)

For pre-4.7:

nat on $ext_if from $air_if:network to any -> ($ext_if)

Similar for ftp-proxy config, and include $air_if in your pass rules.
