On the "Network Settings" page you can make changes to the network settings of your FRITZ!Box.
Inappropriate settings can have the result that the FRITZ!Box user interface is no longer accessible!
Click on the "Apply" button to save your settings. If you leave the page without saving, all of your changes will be discarded.
Guest access enabled for LAN 4
Proceed as follows to set up a LAN guest access connection:
- Enable the "Guest access for LAN 4 enabled" option.
- Then connect the guest device to the "LAN 4" port of your FRITZ!Box using a network cable.
This concludes the setup of LAN guest access.
The connected device has no access to your home network or to the connections of your WLAN guests.
Click the "IPv4 Addresses" button to open the "IPv4 Settings" page, where you can make the following settings:
- IPv4 address of the FRITZ!Box: The FRITZ!Box can be assigned any IPv4 address desired.
- Subnet mask: You can change the subnet mask to the IPv4 address of the FRITZ!Box.
Note:The FRITZ!Box network settings also support subnets that are not pure class A, B, or C networks, for instance 255.255.255.240 or 255.255.128.0.
- DHCP server: You can enable or disable the FRITZ!Box DHCP server.
These settings and the way they interact have a direct influence on the IPv4 addresses on the computers connected with FRITZ!Box.
Click the "IPv6 Addresses" button to open the "IPv6 Settings" page. There you can specify how the FRITZ!Box assigns Unique Local Addresses (ULAs) to local network devices if no IPv6 connection is active.
Static Routing Table
Click the "IPv4 Routes" button to enter IPv4 routes in the FRITZ!Box static routing table manually. This is necessary when there are subnets in your local network which are to have Internet access using FRITZ!Box, and these network addresses are not known to FRITZ!Box.
With this function the FRITZ!Box can synchronize the date and time with time servers in the Internet.
Time synchronization (NTP) enabled
If time synchronization is enabled, the FRITZ!Box synchronizes time and date with time servers in the Internet.
The time server preconfigured in the FRITZ!Box is the following: 0.europe.pool.ntp.org
You can enter a different time server here. It is also possible to enter multiple time servers. The individual time servers then must be separated by commas.
The information on time synchronization in the Internet is generally provided to the network devices automatically.
The timer service of the given operating system is responsible for time synchronization with the time server. In Windows operating systems the timer service is switched on by default.
Network devices connected with the FRITZ!Box that are supposed to synchronize their time with the FRITZ!Box, use the local IP address of the FRITZ!Box in the timer service of their operating system.
In Windows operating systems this information is defined in "Control Panel / Clock, Language and Region / Date and Time / Internet Time". The entry for the time server is the local IP address of the FRITZ!Box or simply "fritz.box" ("time.windows.com" is entered by default).
Additional IPv6 Routers in the Home Network
Allow IPv6 prefixes announced by other IPv6 routers in the home network
With this setting you allow the network devices connected to the FRITZ!Box to receive their own IPv6 prefixes, which are announced by other IPv6 routers in the local network.
Also announce DNSv6 server via router advertisement (RFC 5006)
With this setting you specify that the FRITZ!Box identifies the local DNSv6 server in the local network by router advertisement. Alternatively, the network devices can identify the local DNSv6 server via DHCPv6.
