General information for the Fritz.box VPN function
In order for the Fritz! Box to become the VPN server, first check System / Update, if the latest firmware version is installed. Then, make sure that it is permanently connected to the Internet and that the connection is not disconnected when it is inactive. In order to be able to access the router or the VPN server on the way, you must know its address. Since the address changes every 24h, however, you could theoretically register with a DDNS provider to get a fixed Internet address. However, since your INSTAR camera already uses a built-in DDNS service, you can use the address under Network DDNS in the web interface of the camera.
First go to the AVM services page at AVM-VPN to get the latest version of Fritz! Remote Access for your Windows (Either 32-bit or 64-bit) and then install it by default. The program takes all your security settings and saves them in a configuration file, which you then only have to import into the VPN remote.
