Blocking the computer <name>, since the Internet was accessed from its IP address <IP address> using the MAC address <MAC address>, rather than the MAC address <MAC address>.
With FRITZ!Box child protection, you can specify for each computer how long and during what times the Internet may be accessed. For this the FRITZ!Box identifies every computer using its IP address and MAC address. By changing the IP address or the MAC address it would thus be possible to bypass any restrictions to Internet use defined for a certain computer in the child protection settings.
The FRITZ!Box detects such attempts automatically and immediately blocks Internet access for the corresponding computer.
At the same time, the FRITZ!Box returns the above event message to inform you for which computer the Internet connection was blocked because of an attempt to bypass child protection.
To restore Internet access for a computer with blocked child protection, the block must be removed as follows:
DSL not responding (no DSL synchronization).
Check that the DSL cable is plugged in correctly at the DSL splitter and at your FRITZ!Box. If needed, consult the cable connection diagrams in the manual for your FRITZ!Box. If all the cables are connected correctly and the error message appears again, contact your DSL provider.
DSL is available (DSL synchronization exists).
This status message informs you that DSL synchronization was successful. Your DSL line is now ready for operation.
