When it comes to MAC addresses, each network adapter has one burned in.
A laptop would possess two: one for the hardwire NIC, and one for the
wireless adapter. If you can program your Rosewell appropriately, you
can tell it to allow "guest" NICS who aren't listed in the MAC filter a
single static route through your network to the Internet uplink, and
deny them access to any other machine on the network. The MAC list would
then be used to allow file and print sharing, and other types of
intranet connectivity. You can also use a second MAC filter to totally
deny access to the network for stuff you don't want connecting at all.
Tinker around and see what you can accomplish. Another thought is to use
two MAC lists: one for your trusted computers, and a second for guest
routing to the Internet, and deny access to anything not on the lists.

Hi All

Hey Mark and thanks for that idea, one I never would have thought of and

something I may think of doing in the future but the only problem with 
that would be the cost of additional routers and also wouldn't they have

to be bridgeable? If so not all wireless routers are capable of this I 
don't think. My Rosewill's manual says it can. I do have a backup router

I use for emergency's which is a linksys wr160 but I don't think that is

bridgeable I do have a third but it's a wired linksys and a pretty old 
one so I doubt that one would be. Also my network knowledge is pretty 
basic and setting three routers up and getting them to work together 
would be a major job I would think at least for me. Sorry I didn't 
mention the situation here which is a home/office environment. Also all 
machines are running XP Pro with one machine dual booting Win 98, Vista 
and Ubuntu. All the wife's clients are handled over the internet or by a

phone call. She has no local clients. But that may change somewhere down

the line though.The only people other than me and the wife would be the 
occasional family guest. So The guest would only need internet access. I

would prefer that the lan was not accessible while the "guest" was 
online. My workgroup name is pretty far out there not even close to the 
default.

I will look into the mac filtering end of this as Kenneth Whyman 
mentioned this might work out. The next question is would I need to have

the mac address of the computer or the NIC? I'm guessing the NIC but not

sure on this one.

Thanks again for all your help
