Here is ipnat.conf

#!/sbin/ipnat -f -
#
# THIS EXAMPLE IS WRITTEN FOR IP FILTER 3.3
#
# ae1 - (external) Ethernet connection to ISP, address a.b.c.d/24
#
# ae0 - (internal) network interface, address w.x.y.z/32
#
# If we have only 1 valid IP address from our ISP, then we do this:
#
# To make ftp work, using the internal ftp proxy, use:
#
map ae1 192.168.1.0/24 -> 0.0.0.0/32 proxy port ftp ftp/tcp

#
# For normal TCP/UDP and other IP protocols
#
map ae1 192.168.1.0/24 -> 0.0.0.0/32 portmap tcp/udp 1025:65000
map ae1 192.168.1.0/24 -> 0.0.0.0/32

And here is the output of ifconfig -a, I censored my external address as
a.b.c.d cuz I've been hacked once already this year. ;)

Hope this helps.
