After doing further experiments, I have found the following. MAC address's are NOT passed over a Wireless Ethernet Bridge. Access restrictions will not work on a machine that is on the remote side of the network unless they are IP based. Switching over to a WDS and you can once again use MAC address's for access control. This problem would cause the issues that jsmiddleton4 and I were discussing in this thread: http://www.linksysinfo.org/index.ph...ls-denon-3808-music-server-in-web-mode.35683/ Without MAC's, you can not ARP bind an address. When I go to WDS, the MAC address's are passed by the firmware again. It also effects things like the network map in any windows platform that can display it. In a WEB, the computers on the remote router are unable to be placed on the network map. When you switch over to a WDS, the map then populates showing switches, computers, and links. In speed tests. the WEB is about 20% faster than a WDS, but the WDS is more network friendly, coherent, and IMHO secure.
