BZZT!!! But thank you for playing. A linksys NAT router presents only one Mac address to your equipment. Behind that router, you can have up to (IIRC) 1024 devices, each of which could be another NAT router if you are desperate.

If you are providing network access to people not on your payroll, you are an intentional (albeit possibly unaware) LIR. I did not say unintentional, I said possibly unaware.
