What should I do if I can’t run a publicly accessible Samba share because port 445 is blocked?

Using Samba as a file-sharing service for accessing or transferring files to and from devices outside of your local network is unsecure, as there is a risk of your data being intercepted by third parties.

Alongside this, there are a number of known vulnerabilities with services that use port 445 - these can be exploited by third parties to gain unauthorised access to a device.

We recommend using an alternate file-transfer protocol such as the widely used SFTP (SSH File Transfer Protocol).
