I installed a 951 for a customer the other day as a PPPoE router with firmware 5.20. No matter what I did and how many times I factory reset the thing it would only automatically bring up one automatic PPP mangle rule. Other units including another 951 and a 751 have have always brought up two. I had to manually add the missing entry in. Has anyone else experienced this? It had no problems putting the right pair of mangle rules for L2TP.
