Most likely your ISP configures their network equipment according to PPPoE authentication. Only PPPoE authenticated users have access to the network, other IP packets are dropped.
When you change to a static IP, the PPPoE session ends and your ISP's router starts dropping all traffic from your end.

Your ISP has designed its network this way and it is their policy that only authenticated users have access. You need to contact your ISP about this. Serverfault people will not answer questions on how to circumvent policy. – Tero Kilkanen Jul 08 '16 at 14:30

1@PratikKhadtale, the mechanism is part of AAA (Authentication, Authorization, and Accounting). If you have not been authenticated, you will not be authorized. – Ron Maupin Jul 08 '16 at 15:16

you are using router to dial to pppoe? Or OS, modem?? If the machine picks up such Request Package it answers with an ICMP Echo Reply. If you turn off "Ping from WAN" you simply tell your router that it should not care about any ICMP Echo Requests sent to you. If you have router, check whether you have disabled ping from WAN in router.
