If I may hijack this thread, as the original poster appears satisfied, can I as a beginner ask about routing on a bridge?
I understand that a bridge essentially just accepts a packet on one interface and spits it out the other so that routing decisions shouldn't be necessary, and that indeed the interfaces on a bridge don't even need IP addresses (is that true?). However I don't understand the following:
1. Isn't it wise to have an address on the bridge so's you can Winbox into it if anything needs checking or changing - ie suppose you want to check the health of the wireless card/signal, or scan from it to see if the other end of the wireless link has gone down?
2. If you have such an address for access don't you need a routing entry of some sort so's the bridge device itself knows which interface to spit replies to such enquiries out of?
3. If a wireless link beyond a bridge goes down doesn't everything just get dropped silently by the bridge as it has nowhere to go? How do you actually know when such a thing has happened, beyond the fact that your browser is just sitting there on the screen with the little icon going round and round and round and round?
