12.2 LAN (ext)
12.2.1 Configuring the Interface to the External Network
(LAN/WAN)
The EBW-E100 uses its router function to switch the data traffic between two IP
networks, an "internal" and an "external". The LAN ext interface serves for
connecting the router to the external network. This external network can be
another LAN, which can be accessed via an Ethernet cable. Then, an IP address
must be configured or obtained for the LAN ext interface. This IP address must be
in the address range of the external LAN, into which the EBW-E100 shall route. The
router can configure one or several IPv6 addresses for itself using SLAAC
(StateLess Address AutoConfiguration). If a router with router advertisement
advertises IPv6 address prefixes in the LAN, the router configures itself another
IPv6 address with the advertised prefix in addition to the already configured IPv6
addresses. However, the external network can also be a WAN, which is connected
via an DSL connection. In this case, you must configure the interface for PPPoE
operation, to enable a communication with the WAN via a DSL modem.
Configuration via web interface (menu "LAN (ext)", page "LAN (ext)")
For a connection to a LAN, select the radio button "static IP address".
Then, enter into the entry fields "static IP address" and "Netmask" an
IPv4 address as well as a netmask. The IP address must be an address
from the external LAN, to which you connect the device.
Check the checkbox "Retrieve IPv6 address automatically (SLAAC)" that
the router configures one or more IPv6 addresses automatically.
Enter the IPv6 address of the router in the LAN into the entry field "IPv6
address" or select the link "Generate new ULA" to generate a ULA
(Unique Local Address).
In order to connect the device via DSL to a WAN, configure in the "LAN
(ext)" menu on the "DSL" page the DSL connection first. Select the
"PPPoE connection" radio button.
In order to enable the DHCP client, select the "DHCP-Client" radio
button. The router retrieves an IP address from a DHCP server via the
LAN ext interface then. In order to obtain another IP address for each
host table entry, check the checkbox "Request an additional IP address
for each entry of the host table". Another IP address is requested for
each host table entry and assigned to the LAN ext interface then. The
host name will be composed by the own host name and the host name
of the table entry. All packets that are sent to this additional IP
addresses, will be forwarded to the IP address of the host table entry.
In order to operate the device as bridge, select the "Bridge" radio button.
Then, the LAN ext interface behaves like another switch port.
Save your settings by clicking "OK".
