Internet Sharing Security?

[dpaanlka]

Hello!
I'd like to use a desktop Mac that is connected to ethernet to create a "guest" wifi network, using Internet Sharing. I turned on Internet Sharing in System Preferences > Sharing, and can connect to it successfully from wireless devices.

Although the connected devices can *not* see other shares on my network in the Finder, they *can* see the the desktop Mac it is connected to (which has file sharing turned on). Is there anyway to strictly limit this "guest" network to *only* internet access, and not see the Mac (or anything else) at all?

Thanks!

If File Sharing, Screen Sharing, etc are enabled but restricted to accounts on the Mac and not "Everyone", then Guests might see the Mac, but won't be able to access anything on it.
