Section 3 | Gateway G1 Configuration

Dynamic

In the dynamic network configuration, all necessary network parameters (IP address, subnet mask, default
gateway, primary and secondary name server) are automatically retrieved from the DHCP server. This procedure
requires a DHCP server in your network (usually provided by your DSL router). In addition, you should instruct
the DHCP server to always give the gateway the same IP address. Usually, you do this by entering both the
gateway's Ethernet MAC address (EUI-48) and an address excluded from the pool of non-persistent addresses.
More information can be found in the manual of your DHCP server (in home networks, usually integrated in the
internet router). Make sure that you only have one active DHCP server in your network, otherwise wrong confi-
guration can occur.

Static

By default, the gateway is configured with fixed (static) network parameters. A static configuration offers the ad-
vantage that no DHCP server is required. Even if you operate a DHCP server, static gateway configuration does
not require a change of the DHCP server's settings. It is important to prevent address issues. Make sure that
the IP address you choose is not assigned to another device in your network. For your gateway, select a free IP
address from the subnet that contains your control devices (smartphone, tablet).
Adjust the network parameters to your existing network. Note the settings of a possibly existing DHCP server.
The IP address of your Smart Home gateway has to be excluded from the IP address pool that is used by the
DHCP server to assign non-persistent addresses to devices.
In the following example (see figure 22), a DHCP server configuration is shown, allowing only static IP addres-
ses higher than address 200.
