Phishing website on LAN

Hi!

I want to create a phishing website in my wireless LAN. The idea is:
1. I will leave my router unsecured, so everybody will be able to connect.

2. When some of the computers connected to my wireless LAN makes a request to, say, facebook.com, my router somehow redirects him to a local webpage stored in my computer imitating obviously the facebook's layout.

3. People fill in the login page and the data is sent to me.

4. they are redirected to the actual facebook.com

So, do you think it will be possible? Any idea or tip to start with?

thanks!

ps: i don't have any particular malicious purposes, it's just for fun.
