I have a linksys wrt54g router. i need to block all devices except one from plugging in a wired device into the back of the router. i tried the mac filtering, but i didnt work. Is that for wireless only?

I can also block local ips (192.168.1.x), and was going to go that route and only allow my local computer but i was afraid if i restarted my router or computer the ip would change and i would be locked out.

any thoughts?

If I can remember right there are two mac filtering options on that router, one is for wireless, the other is in the parental control section, and you setup a profile, like block port 80. and put the mac addresses you want to block.
