12.1.2 Set IP Addresses or Retrieve via DHCP
It must be possible to access the MoRoS Modem - ISDN 1.3 in the LAN at a certain IP ad-
dress. Either manually enter a static IP address, or prompt the MoRoS Modem - ISDN 1.3
to retrieve the IP address during each system start and cyclically from another DHCP
server in the LAN.
Configuration with the web interface
To set the static IP address, select "Static IP address" in the menu "Basic set-
tings" on the page "IP addresses", using the radio buttons (Figure 9, page 32
above, position 1).
In the entry field "IP address" (Figure 9, page 32 above, position 2) enter the IP
address of the MoRoS Modem - ISDN 1.3 in the LAN and the network mask .
To retrieve a dynamic IP address from another DHCP server in the LAN, select
the radio button "Activate DHCP client" (Figure 9, page 32, above, position 1).
Save the settings by clicking "OK" (Figure 9, page 32 above, Position 7).
The MAC address of the MoRoS Modem - ISDN 1.3 can be found in the entry
fields for the IP address and the network mask under "MAC address" (Figure 9,
page 32 above, position 3) on this page.
12.1.3 Setting up the DHCP Server
On request, the DHCP server of the MoRoS Modem - ISDN 1.3 can automatically allocate
other devices in the LAN an address. This automatically allocated, dynamic IP addresses
are only valid for a certain time. The validity of the IP addresses allocated by the DHCP
server are controlled via the "Lease time". If there is already a DHCP server in the net-
work, in which the MoRoS Modem - ISDN 1.3 is used, this function must absolutely be
disabled in the MoRoS Modem - ISDN 1.3.
Configuration with the web interface
To set up the DHCP server, activate the checkbox "Activate DHCP server" in the
menu "Basic settings" on the page "IP addresses" (Figure 9, page 32 above, po-
sition 8).
In the entry field "First IP address" (Figure 9, page 32 above, position 4), enter
the first IP address of the address range, from which the DHCP server of the
MoRoS Modem - ISDN 1.3 allocates addresses in the LAN. In the entry field
"Last IP address" (Figure 9, page 32 above, position 5), enter the last IP address
of the address range. The IP address range of the DHCP server must be located
in the same network as the IP address of the MoRoS Modem - ISDN 1.3.
In the entry field "Lease time" (Figure 9, page 32 above, position 4), enter a Va-
lidity period in seconds for the IP addresses to be allocated from the DHCP
server. The default value is 3.600 seconds.
Save the settings by clicking "OK" (Figure 9, page 32 above, position 7).
