Question : Linux as a Wireless-to-Wireless Router

Hello, I've recently been playing around with Linux, and I've noticed that there are some interesting projects online for those who wish to get their feet wet and learn some of the advanced features that Linux has to offer. In particular, there are several guides online on how to turn a Linux machine with two network cards into a router.

This might sound like a dumb or pointless question, but I was wondering whether it is possible to use the same network card to send and receive data; not as a repeater would do, but I would like to use Linux as a wireless-to-wireless router using only one wireless network card. My main goal in doing this is to learn the OS, but this could potentially be a useful project if I were able to use the Linux machine as a firewall, for instance.

So far I haven't been able to find any guide online and I don't think that I can figure out how to do it on my own from the resources I've looked up. Although I am not quite a newbie, any push in the right direction would be very helpful.

Thank you.

Answer : Linux as a Wireless-to-Wireless Router

Taking a second thought about it, it might be possible to route with one NIC, indeed!?
Since routing is being performed on IP level, you could reach your goal by simply assigning 2 different IPs to the NIC.
