LAN configuration
With the help of the LAN configuration you can change the preset values for the com-
puter name and the private IP address for your SE681 WiMAX and configure the inte-
grated DHCP server.
Open the
Advanced Settings
tab and select
Local Network
.
The preset IP address is 192.168.2.1. This is the private IP address of the SE681
WiMAX. This is the address under which the device can be reached in the local net-
work. It can be freely assigned from the block of available addresses. The IP address
under which the SE681 WiMAX can be reached from outside is assigned by the Inter-
net service provider. The default Subnet mask for the local network administered by the
SE681 WiMAX
is 255.255.255.0.
Please note which subnet mask is set when assigning the IP address. The preset sub-
net mask defines the first three parts of the IP address which must be identical for all
network components (including routers).
We recommend that you use an address from a block that is reserved for private use.
This address block is 192.168.1.1 to 192.168.255.254.
Configuring the DHCP server
The SE681 WiMAX has a DHCP server for which the factory setting is active. Conse-
quently, the IP addresses of the PCs are automatically assigned by the SE681 WiMAX.
If the DHCP server is active, you can define a
Lease time
. The lease time indicates
how long the client may use the allocated IP configuration.
Define the range of IP addresses the SE681 WiMAX should use to automatically
assign IP addresses to the PCs. Define the
Start IP
and the
End IP
.
i
If the DHCP server for the SE681 WiMAX is activated, you can con-
figure the network setting on the PC so that the option
Obtain an IP
address automatically
is set up.
If you deactivate the DHCP server, you will have to assign a static IP
address for the PCs that use the network settings.
For more information see the document “Configuring the local area net-
work” on the CD.
Note:
If you select
Never expires
, the IP addresses are never changed. Activate this
option if you want to make NAT or firewall settings using the IP addresses of the
PCs; otherwise you have to assign static IP addresses to these PCs.
