I recently purchased a V6 and noticed that the filtering feature is ONLY supported on the wireless port. I want to ONLY allow MAC addresses that are used in my house to access internet and one one else. I also have a wireless AP attached to one of the ports of the WRT54G and unwanted people can come in from that wireless interface. I tried using the security feature and clicked on ALLOW and put in explicit mac addresses with 24hr allowance to access internet, but that does not do it since configuring like this actually will ALSO allow anyone beside these explicit addresses to connect as well as opposed to ONLY these addresses. Anyone knows how to enable MAC filtering with wired ports? thanks!
