Today I attempted and completed my first install of m0n0wall on and older
p3-600/64mb/floppy/cd/2-nic machine. I gotta say, I love this thing!

It does everything I need it too for right now, but in a few weeks I'll be
setting up a free-ish hotspot for a friend - and I'd love to use m0n0wall.

everything is working perfectly with the captive portal right now, I've
created a login page and a m0n0wall user (no radius) and can log into it
from my wireless laptop. My question is: Can I somehow add a rules to users'
accounts?
Like:
JoeUser, gets X% bandwidth for N minutes

Keeping in mind, this is my first install of m0n0wall and I don't have very
much *nix experience - but I'll get as deep as possible.
I'm on a test network and have backed up the configs :-)

Thanks for any and all help!
