With ReadyCloud going away, a lot of folks are going to be looking for a replacement in order to have remote access to their ReadyNAS, I have been using ZeroTier (instead of ReadyCloud) for some time to do that, so I'm re-visiting it here. You can see my initial thread here: ZeroTier-and-the-ReadyNAS . You can see a general overview of ZeroTier at https://www.zerotier.com/, and be sure to also see https://docs.zerotier.com/getting-started/getting-started/, which shows you how to create your ZeroTier network.
While the ReadyNAS-specific versions still work, they are very old at this point. But the only way to get a GUI for it is to install the appropriate "nt3" version from here: https://github.com/NAStools/zerotierone/releases.
Frankly, you are better off installing (and then configuring) it from SSH so it's the latest and greatest. It does not seem to have anything that can fill the OS partition. You don't really need knowledge of how Linux works to do this install, you just issue these commands from SSH:
ZeroTier Central gives you the network ID to use and the info command above gives you the node address of the NAS so you can authorize the NAS in ZeroTier Central.
Note that as of this date (Jan 25, 2023) I have verified that this install script works with ReadyNASOS6.10.8 on both Intel and ARM systems. The installed version isn't the latest. It's 1.4.0, while 1.8.9 is current, but anything newer seems to have broken dependencies. But it's still a lot more up to date than the nt3 one. There isn't normally any ongoing configuration updating required, so you may never need to go into SSH to control it again. ZeroTier operation does resume after a power cycle.
Next, install ZeroTier on your Windows, Mac, Android, IOS, or Linux system (including a Netgear or other NAS) and they can talk to each other remotely and securely with no need for port forwarding, dynamic DNS, etc. You can have them all on one network, or you can have multiple networks to segregate devices from each other.
As for accessing the ReadyNAS, it now will look like any local LAN device, just with a new IP address. So you use a local log-in to the NAS (not your ReadyCloud ID) and local protocols (SMB, HTTPS, etc. -- even SSH) and local programs/apps. The traffic doesn't flow through ZeroTier. ZerTier Central is only needed so your devices can find each other. In that respect, it's much like ReadyCloud.
But, ZeroTier just provides the connection. If you want to do file sync, you'll need a program/app for that. FreeFileSync is a good option for Windows, Mac, and Linux. SyncThing adds Android to that list, and Resilio Sync adds IOS as well. If anyone has specific recommendations. feel free to add them to this chain.
