SecureLine does not alow connection to NASin local network from Win10 PC

Where can I configure SecureLine to allow conneting to specific devices in the local network, like a NAS

In the settings, under “Network Security”, have you checked “Exclude Trusted (private) networks”? Also, your local network must be private, which is a setting in Windows.

If you are using Avast Firewall it must be set to Private, not Public, for NAS devices to be seen.
