vpn l2tp+ipsec client connects but no internet, what's the problem?

Question

VPN

The bottom line is, there is a vpn client PC, everything worked ok until I installed Mikrotik. vpn server - vpsk linux.
VPN is connected, but there is no access to the Internet from the browser , but skypeak, teamviewer works. And on the second computer from the same local network, everything is the same.
I connected an android phone to vpn - everything works fine. In Mikrotik, just in case, I opened the ports (screen).
What could go wrong? before that there was a zyuksel, everything was ok.
