Yes, I use PPPoE, it's always been that way on R2. To get the speeds right, I have to use R2 along with my ISP's router, but I don't want to have two routers. I don't think there's any need for two!
When I change routers, I have to call my provider so they can clear the router's MAC address. Since the MAC address is the same as the R2 router's, they only allow one MAC address at a time, and I have to do this procedure every time!
