Router is configured so the computer is connected to Internet through router's Wi-Fi and pinging 1.1.1.1 from the computer is going fine.
Then I enable previously disabled L2TP client and pinging from the computer goes down but pinging the same IP from terminal in Winbox still going fine.
L2TP client is "C"onnected and "R"unning. It adds default route with distance 1. Below are two screenshots of Routing table before VPN client is connected and after.
Does anyone can suppose why?
