NAS on X750v2

Hello

How to set up NAS on X750v2? Also I need Tor.

No, I will NOT downgrade because of vulnerabilities.

Any chance to set it up on 4.x?

The only way is this: How to install nas functions manually

But it is 16MB! No storageā€¦

Any ideas?

Also how to set up Tor?

You will need to configure extroot before installing: [OpenWrt Wiki] Extroot configuration
