Is relay access more secure the port forwarding?

i know it is slower, but it should also be more secure, as no additional ports are open.

is the my cloud up-to-date with all debian updates?

I think thats very important for devices accessable from remote to have everything always up-to-date.

Hi,

You are right, relay access it’s slower

Regarding the updates, WD tries to release a new firmware with all the information to improve the drives functionality.
