Howto? 2 interfaces, same network, same gateway
Hello Summary: I have ifplugd managing eth0 and wlan0 (both dhcp). When I plug in the cat5 (which brings up eth0) applications which have already bound to wlan0 stop working, obviously because wlan0 for some reason is unable to get non-local packets out that interface. I figured if poodoze is able to have both interfaces working, then linux must surely be able to do it as well. The
