I have many hosts behind home modems that I need to send commands to.
I know that it is possible to configure port forwarding on the modems and access to them through the specified port but it will put me in a lot of trouble(IP tracking of all hosts, configuring many types of modems to make them do port forwarding)
knowing that I have a server with a static public IP address, is there an alternative to make my hosts contact the server so I can send commands to them?
I also have the possibility to develop the a script that does this but it don't think that's a reliable/secure solution?
