How can I restrict view pemissions to a node related child nodes? Let's say I have a parent node with ID equal to 233 that has the following related nodes: 234, 235, 236 (in a relationship field).
Is it possible to restrict access to paths node/234, and node/235, if they are a specific content type, but still show them for the same users in a embedded view inside a local task of ID equal to 233?
Looking at the comments I realized that in my case at least the best way of limiting the access  for unauthorized users (anonymous mainly) is to not publish the child nodes. And I removed the 'published'='yes' filter in the view itself so I can show those nodes in the parent template. And it works nicely. Thank you for the tips.
