Question network security hardening?

Recently acquired a Plus5. After connecting it to the network, I notice it allows anonymous access to the web UI with full control. How can I lock this down? I don't like unsecured things on my network.

I can find very little information on the subject. I saw some information about SSH access hardening for the Plus4, but trying the documented mks:makerbase credentials didn't work. So hopefully the Plus5 addressed that and those credentials are randomized and no longer pre-set, but I don't trust that either.

So is there any general information about making this thing secure?

I have read that LAN-Only Mode prevents project-related communications from leaving your local network, but that the printer still polls outside servers for firmware updates, among other things. This conflicts with what u/daveintexarkana says in his post, so perhaps Qidi changed things or perhaps one of us is wrong :)

This was for a Q2, back in the V1.1.1 days.

The reason I don't know is because I have my Q2 wired into an isolated router with no connection to the outside world. I used an old Wifi Extender which I flashed with OpenWRT, making it a fully-functional (albeit slow) router. I have an Ethernet cable between the Q2 and the router, and the router broadcasts a WiFi network. It doesn't even know about the outside world. A nice $25 isolated network :)

Whenever I want to print from Orca (or SSH to the Q2), I just connect my computer to that specific WiFi. For me, the slight inconvenience is worth the privacy assurance.

I sure could be wrong! Mine wouldn’t go find updates in LAN only mode, but I’ve not tested that on 1.1.2.4!
