Description of the menu options
ELSA LANCOM DSL/10 Office
R43
Setup/DHCP-server-module
This menu allows you to enter settings for the DHCP server. The menu has the following
layout:
State
On: The device operates as a DHCP server
Off: The device does not operate as a DHCP server
Auto: The device regularly checks whether there is another DHCP server in the LAN. If
not, it operates as a DHCP server and issues IP addresses to local clients.
If there is no IP or Intranet address entered in the TCP/IP module (e.g. delivery status),
the router will issue IP addresses from the address range 10.0.0.2–10.0.0.253 to all
DHCP clients in auto mode.
Start-address-
pool
End-address-
pool
The IP address assigned is taken from the address pool selected ('Start-address-pool' to
'End-address-pool'). Any valid addresses in the local network can be entered here.
If 0.0.0.0 is entered instead, the device will determine the appropriate addresses (start
or end) from the settings under 'Setup/TCP module'. The procedure is as follows:
K
If only the IP address or only the Intranet address is entered, the start or end of the
pool is determined by means of the associated network mask.
K
If both addresses have been specified, the Intranet address has priority for
determining the pool.
K
The start address of the pool is either the address given in the DHCP module or the
first valid address in the local network.
K
The end address of the pool is either the address given in the DHCP module or the
last valid address in the local network.
A valid address is then taken from the pool for the IP address. If the computer was
already assigned an IP address at some point in the past, it requests this same address
