IP Address/Subnet Mask LAN
Two network devices can only communicate with each other if they have a unique name (address).
In IP networks, an IP address is used for this purpose. It ensures that the individual IP packets reach
their proper destination.
The IP Address and the Subnet Mask specified here are used to address the Gateway 400 in the net-
work.
DHCP Server LAN
A DHCP server enables a computer to be fully integrated in an existing network automatically with-
out any further configuration. The computer must only be set to automatically obtain an IP address
(see Chapter 1.4, page 10). The automatic assignment of IP addresses can be restricted to a specific
range of IP addresses (Start IP Address to End IP Address). You can also specify how long the assigned
IP addresses will remain valid. After this time, each computer will be assigned a new IP address. The
assignment of IP addresses is carried out for network devices that are connected via the LAN.
Distribute LAN IPv6 addresses (Router Advertisements activated)
Here you can configure the IPv6 prefix(es) for your home network. The current IPv6 prefix provided
by your ISP is shown under Provider prefix.
If Activate Router Advertisements is enabled but no IPv6 prefix, LAN has been configured, the Pro-
vider prefix supplied by your ISP will be automatically distributed in your network.
If you do not want the Provider prefix to be distributed in the local network, you must ensure that
the option Router Advertisements is disabled.
5.6.1.2 Static Routing
Here you can enter static routes for networks, which can be accessed via the LAN interfaces. Con-
nections to the WAN interface are configured under Internet | Additional Features | Static Routing
(“Static Routing” on page 25).
Click New to open a screen dialog with the following settings:
Name: Any name for the route.
Address Type: IPv4 or IPv6 depending on the address range of the external network.
Destination Network: Address range of the network devices to be reached.
Gateway: Address of the router to the destination network.
Interface: Selection depends on the configured DSL or WAN interface.
Click Save to save the data of the route.
Attention
If you do not have a basic knowledge of network settings, please do not change the de-
fault settings. Any changes to the settings in this screen dialog may cause the Gateway
400 to become inaccessible. If this should happen for some reason, reset the Gateway
400 to its factory settings. Please refer to Chapter 2.3.2, page 15.
Note
Default setting: Start IP Address 192.168.100.50, End IP Address 192.168.100.80. If the
IP address range for the DHCP server is changed, the range of assignable fixed IP ad-
dresses will automatically change as well.
