DNS don't want to be my friend

Hi!
I have MikroTik RB2011UAS-2HnD-IN

After setting up pppoe-client , successfully connected to the provider
DNS resolved and remote requests are allowed
From console I can ping all provider’s servers


But after ping google.com I see that 173.194.87.78 request timeout
Can smbody help with it?

Doesn’t sound like a dns problem.
Insure there is a default route in “/ip route”.
Insure there is a masquerade in “/ip firewall nat”.

!!! I masqued ether interface instead of pppoe
Thanks!
