@scottalanmiller What is the best backup strategy?
Snapshot of VMs and workstations + backups of both, and comply with the 3-2-1 rule?
Or is there a better alternative?

I used a VPS (MeshCentral) hosted in Canada for over 2 years without any problems.

A few years ago I met a bit bitdefender.
Leaving aside the antivirus part.
You can control mobile devices of iOS and Android users, block websites, lock screen and remote wipe.
Also in windows you can block websites etc.

For the corporate version, the licenses are for devices and have a centralized administration console, you can select cloud at no cost or on-premise.

For something so small I also think a family or small business license can work but in this case you should install the additional parental control application.

Taking into account that you must opt for a cloud solution
The best thing would be to go for Private Cloud.

This was it. What a dumb way to have that worded!!

Sorry, google translate.
But it's good that it was fixed.

It seems that in the WAN configuration there is the Port-Binding option, it assigns 1 port to a specific function (IPTV for example)

Also in LAN there is a DHCP Binding option

Maybe disabling or changing any of these options will help you.

These brands have switch and Poe switch, Ruijie also has a router.

@scottalanmiller
Thanks for the explanation!

@scottalanmiller
Does this mean that the AV-Test and AV-Comparative information are part of the scam?

@scottalanmiller

Seriously, it is a shame to know about this, I use it for some computers with Windows and Android and iOS for my family.

Is there an option to protect Android and iOS devices or is it unnecessary?

Bitdefender can be an option, includes a cloud management console or can be on-premises.
If my memory does not fail it has support for windows, macos, linux and android and ios mobile devices.

A second Proxmox Backup Server at your remote site and use the Remote option and Sync Job to sync datastores.

When considering security cameras, it is best to opt for cable (with PoE, Ideal), you can look for:
Avigilon
NVR: PRO 16-PORT (Includes switch with 16 PoE ports)
Cameras: H5A or H4ES
If you are looking for something cheap
Hikvision / Epcom
NVR: XR416 (US) (Includes switch with 16 PoE ports)
Cameras: XB-26ZH-US or XT-26ZH-US

You can consider Yealink his MVC line is compatible with Teams but you must request it.
