Thank you once more Mr. MRU.

Using the pppoe credentials from my ISP, i configured them on the WAN NIC. When i run pppoe-client monitor, it indicates it is connected.

I equally enabled /ip dhcp-clent on the WAN NIC and when i take >print detail, it gives me the details like the IP, gateway, dns1, dns2 etc of the provider. i am able to ping the ip, the gateway but NOT dns1 or 2.

i have also masquerade my LAN which is 192.168.1.1/24 and dhcp

Using /ip firewall filter, i have also configured firewall to protect the router.

i have even set /ip dns set allow-remote-requests=yes

All things being equal, it is supposed to be browsing but disturbingly, it is NOT. Can anyone gives me more advice like Mr. MRU did please?

God Bless You

You are pinging DNS servers from router or from computer in your local net? IF you ping from router, then you should call your ISP, because its DNS is unreachable.
Other thing you could do is to ping 64.233.183.99. IF you able to reach this address then your connection to global net is OK, only DNS isn't working. In this case you can try one of public DNS servers:
