In order to modify the network settings, the Lufft I-BOX and the PC have to be part of the
same physical network. A direct link using a patch cable from Lufft I-BOX to the PC is also
possible.
6.2.1
Managing network parameters
The Lufft I-BOX distinguishes between two modes with respect to its network-side basic
parameters:
Static.
DHCP
As shipped static address assignment is enabled.
Switching between DHCP and static TCP/IP-Settings can be done in Settings->Network
6.2.1.1
Static
The IP address, subnet mask and gateway are stored in the non-volatile setup of the Lufft I-
BOX. The parameters set in this manner remain intact even after power interruptions and
resets, until they are changed via web based user interface.
6.2.1.2
DHCP
If automatic address assignment using DHCP is enabled, the Lufft I-BOX attempts to obtain
its IP parameters from a DHCP server located in the network. If no DHCP server is in the
network or if the attempt to obtain an IP address is rejected, the Lufft I-BOX operates using
the factory default IP address 190.107.233.110. When switching from Static to DHCP mode,
this default IP address is defaulted to until valid parameters are assigned.
6.2.2
Network name
To support an automatic update of the DNS system through the DHCP server, the Lufft I-
BOX identifies with a network name. The network name is set to
“lufft-i-box”.
