Even worse you really can't have the same subnet on 2 interfaces... Like here: 192.168.0.5/24 on interface ether1 192.168.0.6/24 on interface ether2 Both gateways are 192.168.0.1. The problem is that when the router tries to go to the gateway, it doesn't know which route to use (.5 or .6). What I wo...

Problem with multicasting software to clients is error correction. Multicasting is UDP, in addition to the fact that the wireless itself doesn't do error correction when multicasting. You could only multicast something like music or video. You could use *broadcasting* (you know, x.x.x.255) which sti...
