hi, if i try to use the "Connect on Demand" feature the routers WAN mac changes to 00:00:00:00:00:00 after a few seconds and i'm unable to connect to the PPPoE server anymore. The mac change is constant...means reboot does not change a thing. the only way to get the mac back is a hard reset or to set it to HeartBeat Signal or static ip. Am i doing something wrong? Or is it a problem with the firmware itself? Thanks in advance!
