Read the book "Linux Firewalls" by Robert Ziegler. It is a little
outdated now, but he publishes scripts in the book which show how to do
routing. I do simple routing which is similar to yours and use the
scripts Ziegler provides to make it happen.
The book "Linux Routing" by Brockmeier et al may also be a little
outdated but gives the most complete treatment of routing that I've read.
