How do I set up port forwarding?
Step by step would be nice.

I know I need these files:
e-smith-packetfilter-1.13.0-04.noarch.rpm
e-smith-portforwarding-0.1.0-20.noarch.rpm
But what do I do after I download those? Where do I put them? How do I install them? What do I do?
If there is a document on this info, please give me a url. Thank you.
