FRITZ!Box reports "The IP address is not available"
When you try to set up port sharing in the FRITZ!Box, the following error message is displayed:
"An error occurred. Error description: The IP address is not available."
1 IP address is located in the guest network
2 A network adapter is using several IP addresses
You cannot set up port sharing in the FRITZ!Box for devices that use multiple IP addresses with a network adapter or MAC address. The FRITZ!Box does not support devices that use several IP addresses with the same MAC address (for example virtual machines with manually assigned MAC addresses that are used by several devices in the home network).
