will only be able to access your device over this IP address. The device will no longer
obtain an IP configuration dynamically over DHCP.
Example of subnets
If your device is connected to a LAN that consists of two subnets, you should enter a
second IP Address / Netmask.
The first subnet has two hosts with the IP addresses 192.168.42.1 and 192.168.42.2, for
example, and the second subnet has two hosts with the IP addresses 192.168.46.1 and
192.168.46.2. To be able to exchange data packets with the first subnet, your device uses
the IP address 192.168.42.3, for example, and 192.168.46.3 for the second subnet. The
netmasks for both subnets must also be indicated.
Here is an example for an IPv6 address:
Your device can act either as router or as device at one interface. In general, it acts as
router at the LAN interfaces, and as host at the WAN and PPP interfaces.
If your device acts as router, its own IPv6 addresses can be created as follows: a Link Pre-
fix can be derived from a General Prefix or you can manually specify a static value. One
host address can be created through
,3 3
, for additional host addresses you can
specify static values.
If your device acts a router, it commonly distributes the configured link prefix to the hosts
through Router Advertisements. A DHCP server may distribute additional information to the
hosts, e,g., the address of a timer server. A client can create its own host address either
through Stateless Address Autoconfiguration (SLAAC) or have this address assigned by a
DHCP server.
In order to make use of the router mode described above, use the following settings in the
menu LAN->IP Configuration->Interfaces->New: IPv6 Mode =
?3
, Transmit
Router Advertisement =
7+
, DHCP Server
7+
and IPv6 Addresses = Add.
If your device acts as host, it has a Link Prefix assigned by another router through Router
Advertisements. The host address is then automatically derived through SLAAC. Additional
information like, e.g., the General Prefix of the provider or the address of a time server can
be received through DHCP. Use the following settings in the menu LAN->IP
Configuration->Interfaces->New: IPv6 Mode =
%+
, Accept Router Advertisement
=
7+
and DHCP Client =
7+
