is having a cable modem on a LAN illegal

[Yang]

I have 7 NICs, 5 computers, a hub, lots of cat5, and a cable modem. Is it aginst the law or aginst @home rules to get all the computers on the internet only paying for 1 IP? I want to do what the "cable modem on LAN" section of this site tells you how to do and really I don't care if it is leagle or not but my dad won't let me unless I can assure him we won't get busted for doing it. So IS it leagle or will we get in trouble?

Is there actually somebody monitoring the bandwidth and ports for ALL the computers using (in my case) cox cable? It dosen't seem very likely but I guess that dosn't help convince my dad any. What if I called cox? Do you think I would get an answer on if it is ok or not. I really don't want to pay $8.00 per month to do the same thing I could do on my own. How do you sugest I find that contract? I'll have to read that, I probably should have done that before I asked this question here, oh well.

Umm correction on my original question. I just copy pasted the question from the speedguide forum so I should say the "cable modem on LAN" article at www.speedguide.net not this site sorry.
