Well, as we all know, if you have two NIC cards, you can turn your Linux box into wired gateway/router.

What if I have a wireless card, a NIC and use NAT/MASQ to use as access point/router for wireless network? Linksys WRT54G is based on Linux right? So can I turn my box to use as wireless access point if I have one wireless NIC and one regular NIC on my box and then one wireless card on the other?

Do you guys know of anyone who have done it? Or is it really based on the specialized hardware? Any pointers?

TIA ...
