If you look in
You'll see what you're looking for.
The IP masquerading code will only work if IP forwarding is enabled
in your kernel; you can do this by saying Y to "/proc
filesystem support" and "Sysctl support" below and then executing a
echo "1" > /proc/sys/net/ipv4/ip_forward
from a boot time script after the /proc filesystem has been mounted.
Enabling masquerading automagically enables ip_always_defrag too.
