You will have to pick from many different solutions, for each remote environment and each host and manage them all by yourself. TeamViewer and AnyDesk are probably the only solutions (at least trustworthy) that could run on multiple OS and allow remote access by IDs, instead of IPs, which is essential in your use-case. There are other less trustworthy and secure solutions available, like "Ammyy Admin" and "AeroAdmin", but they look and feel really sloppy and have many feature limitations.
There is also a possibility of creating tunnel VPN connections from each host to one VPN server (remote hosts will initiate connections), so you will be able to access different networks and hosts on them over the Internet. This is of course depends on how strict firewalls on remote locations will be, but if you will go that route, you can use essentially any remote management software you like. For that case, personally I recommend NoMachine, which could be used for free, on any major OS and also it is the only remote desktop solution in the World that allows you to authenticate by private-key. I think, you can achieve this by using OpenVPN, since it is less firewall dependent than IPSec. -- With kindest regards, Alexander. ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org ⠈⠳⣄⠀⠀⠀⠀
