Hi All, So while I am a slight noob at this, I can tell you I'm a little smarter then the average noob. I was able to "unbrick" my router the hardcore way when it completely died mid-firmware flash, and have successfully been able to set up a WDS with an Apple AirportExpress, WRT54G, and even been able to hook up my xbox (before it broke) to the airport and all worked well. My problem is this - lately some strange mac addresses have been showing up under my DHCP Client List (not my "wireless" client list!). Is this users that are catching onto my AirportExpress wireless signal (which is a "repeater" mode within the WDS)? If it is, or isn't, how can I ban these specific mac addresses from accessing the signal? The MAC filtering only seems to ban wireless clients showing up on the "wireless" client list. I have gone into the "advanced routing" tab and denied internet access to the rogue MAC addresses, but I'd like to kick them completely. My main problem is I cannot add a simple encryption (not even WEP) to the signal because of the AirportExpress (it's a small miracle alone that I got it working with a non-Apple router!), I already have the SSID broadcast turned off, but these same few MAC addresses show up. Here is what I am currently running: WRT54G - running DD-WRT #22 Mac G5 connected directly to the router AirportExpress connecting in WDS mode as a signal repeater G4 Powerbook connecting with wireless and 2-3 Rogue MAC Addresses (that I know are neither the hardwired G5, G4 powerbook, OR AirportExpress) Let me know what you all think!
