Setting the operating mode
Via the operating mode, you define the role your SE680 WiMAX will play when estab-
lishing and administering Internet connections.
You can run your SE680 WiMAX in the following operating modes:

To change the operating mode, open the Advanced Settings tab and select Oper-
ating Mode from the menu.
When you change the operating mode, your device is restarted.
In
Bridge mode, the following functions are no longer available:

The DHCP server of the SE680 WiMAX is deactivated (

page 29) because the
network components receive IP addresses in the public network.
If you want to access the configuration program of the SE680 WiMAX via your PC,
you must connect the PC directly to the indoor unit LAN port. You must also tempo-
rarily assign it a static IP address in the address range of the SE680 WiMAX. If you
want to use the Internet again after this, reset your PC to “automatic IP address”.
For details see the document “Configuring the local area network” on the product
CD.

The firewall of your SE680 WiMAX is disabled and cannot be enabled (

page 26).

The NAT function of your SE680 WiMAX is disabled. This means that the functions
Port Forwarding (

page 27) and Exposed Host (

page 28) are not available.
If necessary you may have to protect your network components against unwelcome
access from the Internet by appropriate means (e.g. firewall software).
Router Your SE680 WiMAX serves as an Internet router for the network compo-
nents connected to the indoor unit LAN port, i.e. it establishes the connec-
tion to the Internet and ensures the transfer of the communication data to
and from the Internet (default).
Bridge The network components initiate and control their Internet connection them-
selves. Your SE680 WiMAX only allows the communication data to and
from the Internet to pass through.
