FRITZ!Box 6840 LTE Service - Baza wiedzy
FRITZ!Box reports "The IP address is not available"
When you attempt to set up port sharing, the following error message is displayed:
"An error occurred. Error description: The IP address is not available. Please enter your data again. If the error occurs again, please consult AVM Support."
1 IP address is located in the guest network
2 IP address is located in another IP network (subnet)
You cannot set up port sharing for devices that are in a downstream IP network (subnet), for example in the IP network of an additional router connected to the FRITZ!Box. The FRITZ!Box does not support setting up port sharings for devices in other IP networks.
3 Multiple IP addresses for the same MAC address
You cannot set up port sharing in the FRITZ!Box for devices if they use multiple IP addresses for the same 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).
