Router RB951 has been disconnecting and connecting some PPPoE clients for the past 3 weeks. I have been using these settings for six months now i have never experienced such problems. The PPPoE clients are 26 using tender router. Disconnected users get this message on the tender router board, "Dial up Successfully, but cannot surf the internet. Please contact your ISP!" When the user restart their router s/he surf the internet then after sometimes it gets disconnected again.
Please help solve the issue. Below is my configurations.
