2.4 Operating description

When the Teldat 4Ge boots up, its Ethernet (WAN) interface comes up without an IP address. It uses the DHCP pro-
tocol to request an IP address and only accepts the one offered by the corporate router, rejecting offers from other
DHCP servers connected to the corporate network. This is achieved by setting up the corporate router as a DHCP
server and programing it to only handle IP address requests from a Teldat 4Ge. Apart from offering an IP address,
DHCP is also used to convey configuration information to the Teldat 4Ge.

identified and the configuration information sent to the Teldat 4Ge.
