LAN interface setup
5.1
Overview
Ethernet switch or hub
The LAN interface consists of 1 to 4 switched Ethernet 10/100 BT RJ45 connectors.
An option enables to shape a hub instead of a switch for test purposes for instance.
IP address of the Router on the LAN interface
A fixed IP address must be assigned to the LAN interface of the Router.
DHCP server
The Router can also behave as a DHCP server for the devices on the LAN interface.
Remote users IP addresses allocation
If remote users PCs are supposed to connect to the devices of the LAN network, a pool of IP addresses
belonging to the LAN network has to be reserved for them.
The addresses reserved for the remote users must not be allocated to other devices of the LAN network.
Example :
IP address
Remark
LAN network
192.168.12.0 / 24
From 192.168.12.1 to 192.168.12.254
Netmask
255.255.255.0
Router IP addr.
192.168.12.1
Remote users IP pool start
192.168.12.2
In this example, two remote users can
simultaneously connect to the LAN network; one
will receive the IP address 192.168.12.2 and the
other 192.168.12.3.
Remote users IP pool end
192.168.12.3
IP addresses available for the
devices of the LAN network
192.168.12.4 to
192.168.12.254
Identification of the devices connected to the LAN network
The identification of the devices connected to the LAN network can be stored into the Router.
The access to an identified device can then e allocated individually to the remote users.
Wi-Fi access point
When the optional Wi-Fi interface is set-up as an access point, the devices connected to the Router through
that Wi-Fi network belong to LAN network.
As a consequence, their IP address belong to the IP domain of the LAN network.
