Setting up the DHCP Server
On request, the DHCP server of the MoRoS LAN PRO 2.0 can automatically allocate an
address to other devices in the LAN. 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 LAN PRO 2.0 is used, this function must absolutely be disabled
in the MoRoS LAN PRO 2.0.
IP addresses, which are in the IP pool and for which a connection to a MAC address exists,
are exclusively reserved for this DHCP client. The IP address is thus not in the IP pool
anymore. No IP addresses should be selected from the IP pool for this MAC IP address
connections. The pool should only be available for the DHCP clients, for which no MAC
address is known or is to be considered.
