Yes, I think so.

This is a very common setup.  You should be able to find loads of
information on the web, including some examples that will be almost
exactly what you need.  Might I suggest a couple of links that I have
bookmarked and find very useful (beware the line wrapping):

Iptables tutorial

http://people.unix-fu.org/andreasson/iptables-tutorial/iptables-tutorial.html

Rusty's official packet filtering howto

http://www.iptables.org/documentation/HOWTO/packet-filtering-HOWTO.html

The second one in particular should have you up and running in no time,
the first link is good for more complicated operations and to get a
better understanding of how it actually all works.

Good luck,

Lucas
