How to portforward on a Westell A90-750015-07Router (Minecraft)?

I'm running on a verizon network, and my Minecraft server is up and running. I can access it, but I'm wanting my friend to do so and he can't. I'm running on bukkit if that makes it any better. I really want to make this server public, so any type of help would be great!

Added (1). I tried those, but it doesn't seem to save/work. I'm not sure why.
