Hirschmann NetModule AP3400 User Manual page 32

If a DHCP server is not available, or the board fails to receive dynamic IP from the DHCP server, then
the Fallback IP address will be used. You can access the board's WEB GUI by using this address. By
default, Fallback IP is 192.168.1.200. To access the board by this address, connect your computer via
ethernet cable to the board's WAN port, and manually configure your computer to use 192.168.1.254
IP address on its ethernet port.
Static IP mode Static IP mode can be selected when a DHCP server is not available, or when you
need a more advanced WAN configuration. In this case you must manually enter the main network
parameters, which would normally be assigned by the DHCP server.
IP address - specify an IP address for the device.
Netmask - specify a subnet mask for the device.
Gateway - specify a gateway address for the device.
DNS servers - specify one or two DNS addresses.
LAN Configuration
By default AP3400 boards have one Local Area Network (LAN) created. The default LAN network has
a name "Local Network", which you can change. This network cannot be removed, but its parameters
can be changed.
By definition a local area network (LAN) is a computer network that interconnects computers in one
physical location such as a building, office or home.
The default local network has 192.168.2.1 IP address configured on the board.
This LAN network has a DHCP server running on board, so whenever you connect your computer or
another smart device to this network (by Ethernet 1 port or WiFi network), that device will receive a
dynamic IP address in range 192.168.2.2-192.168.2.254.
IP address - device IP address in LAN network (default 192.168.2.1). DHCP server - enable a built-in
DHCP server, that provides IP address for devices connected over Wireless and Wired interfaces on
LAN side (interface).
IP address from - specify the starting IP address of the DHCP address pool.
IP address to - specify the ending IP address of the DHCP address pool.
Lease time - specify the expiration time for the IP address assigned by the DHCP server.
Click Add to add additional LAN networks, each of the networks must have a different IP address
range.
DHCP Server The Dynamic Host Configuration Protocol (DHCP) server dynamically assigns an IP
address and other network configuration parameters to each device (client) on the network, so they
can communicate with each other, and with other IP networks.
Static DHCP lease - if you want your smart device (client) to have the same IP address assigned
every time it connects to this LAN network, then you can add a Static DHCP lease. For this you must
know a MAC address of your device - a unique hardware identifier, that all network devices have.
You can usually find your smart devices MAC address in the Network information page of AP3400
