When the mobile communications function is used, the

Once this function has been set up, the “Internet > Mobile

Communications” menu is always available, even when the

USB modem has been disconnected.

7.4 Internet Connection over LAN 1: FRITZ!Box as a Router

You can use the FRITZ!Box at an already existing Internet ac-

cess via the LAN 1 socket. To do this the FRITZ!Box is connect-

ed to the router or network. For this kind of connection the

FRITZ!Box can be configured as an independent router or as

an IP client in the existing network.

Configuring FRITZ!Box as a Router

You can configure the FRITZ!Box to work as an independent

router to provide a network with its own network address

range.

1. Connect the FRITZ!Box to the router or network with a ca-

ble as described in section Connecting with a Router or a

Network on page 19.

2. Open the FRITZ!Box user interface.

The “Mobile Communications” menu is not available

until the UMTS/HSPA modem has been connected to the

USB port of the FRITZ!Box.

Due to technical limitations on the part of the mobile com-

munications network providers, some restrictions may arise

for Internet telephone calls and for applications requiring an

incoming connection. The same is true for using port for-

warding, sharing USB storage, remote access via HTTPS, Dy-

namic DNS and VPN. Contact your network provider for de-

tails on any restrictions that may apply.
