if it doesn't come with ipchains installed and a script
to start masquerading on connection, then it hardly be
said to support masquerading out of the box.

as well as ipchains, you'll need a script that looks
something like:

  ipchains -P forward DENY
  ipchains -A forward -i $extif -j MASQ

you can run this script manually, or have it run
at boot time or at connection time.

isn't the rest of your network connected to the masq host,
already? anyway, get another nic and/or read the
net-4-howto. if you are going to have 2 addresses on the
same nic, you just need to use ifconfig to add the 2nd
address.
