I am running an older Wireless B Linksys router behind a WRT54GL. Wireless B has DHCP disabled and static IP has been set on this unit. Reason for running B router is that one old G adapter cannot do WAP so still need to run Wireless B on WEP behind the WRT54GL. I have setup, at least what I thought I have setup, MAC filtering so that only the 1 MAC address can connect to the Wireless B router. Just logged in today to see that I see 1 green mac address, the one I had allowed. But I also see 3 MAC addresses that are not part of my own LAN. They are all in red inside the Wireless Active MAC Table on the wireless B router. Has there been a breach? Or does the red colour indicate there was an attempt but was denied? A little worried now.
