IPsec between two Mikrotik: there is a ping, there is no access to resources via IP. What to do?

Question

Mikrotik

Hello.
I set up a tunnel between two Mikrotiks using this video https://www.youtube.com/watch?v=_AyZ0kH76Oc
Mikrotik's config is standard out of the box (lan, wi-fi, masquerade are already configured), i.e. the firewall was already configured by default, etc., I just added what is said in the video. Ping between networks appeared, but smb refuses to work. Tell me where to dig?

Answer 1

I disabled the fasttrack connection rule in the firewall , which was out of the box, the connection appeared. Strange, judging by the manuals, it is only to unload the kernel, skipping packets without processing.

Answer 2

and the client device will know that my route needs to go through the tunnel? (hint of correct routes)
