Description:
With the ongoing migration of ISDN connections to All-IP, the ISDN connections available at sites are being converted into additional DSL connections. In order to provide this new bandwidth to the whole of the network, the router needs to be connected to the new DSL line.
If the DSL connection of the gateway is already in use, a LANCOM VDSL router can be connected upstream as a pure DSL modem. The access and VoIP data continue to be stored in the main gateway. This allows additional DSL connections to be transparently integrated into the existing scenario.
As of LCOS Version 10.20, all LANCOM VDSL routers can be switched to DSL Bridge mode. This allows the use of the devices as a pure DSL modem.


Hinweis

The Bridge mode refers only to the internal xDSL modems. If the router (additionally) has a built-in LTE modem, the LTE modem can not be operated in bridge mode!




Requirements:



Procedure:
1
.
) Configuration steps on the router used as a modem (Modem router):
1.1) Connect the LANCOM router, which is to operate as a modem, to the VDSL port.
1.2
Connect the main gateway to the LANCOM modem by means of an Ethernet cable.
) Open the configuration of the Modem router in LANconfig and go to the menu Interfaces → LAN → Ethernet ports.

1.3
In the menu Interfaces → LAN → Port table, combine the LAN used and the xDSL interface in a free bridge group.
In this example, the logical interface LAN-1 and the interface XDSL-1 are combined in the unused bridge group BRG-2.
Also make sure that used
) Edit the Ethernet port to be used for administration of the router (in this example ETH 1) and make sure that the logical interface LAN-1 is
also assigned to the correct physical port (for example, ETH-1
assigned to it.

1.4) Edit an unused Ethernet port to be used for the connection to the gateway router (in this example ETH 4) and select the interface LAN-2 as Interface usage.

4 Switch to the menu Interface → WAN → Interface Settings → xDSL modem operation and configure the VDSL port to Bridge Mode.
  • For operation on VDSL connections no further parameter needs to be changed.
  • For ADSL connections (for example, Deutsche Telekom), you must configure the ATM parameters to the following values:
    • VPI: 1
    • VCI: 32
    • ATM-Modus: LLC-Mux

6) Make sure, that the option Connect by using a bridge (default) is selected and switch to the menu Port table afterwards.

1.7) Make sure, that no Bridge group is assigned to the logical interface LAN-1.

1.8) Edit the LAN interface selected in step 1.4 (in this example LAN-2) and the xDSL interface (in this example xDSL-1).
Assign an unused Bridge group to both interfaces (in this example BRG-2).

1.9) The Port table has to appear as shown below afterwards.

Info

Depending on your Internet provider it is possible that the parameters VPI, VCI and the ATM mode have to be changed. Please ask your provider if necessary.

IPv4 → General → IP networks

menu,

assign

a local

an IP address from an unused IP

address

range

(for example,

to the network INTRANET (in this example 192.168.3.254/24 ) and make sure that the interface LAN-1 is selected (see step 1.3).


Hinweis

The assignment of an unused IP address range is mandatory. If an IP address from a local network configured on the Gateway router is entered on the Modem router and an IPoE remote site with an IP address from the local network is created on the Gateway router to ensure Management access (see step 3), the local network and the WAN (MANAGEMENT) will have the same IP address range. This will lead to routing problems!

) Set up the Internet connection on the main gateway (Gateway router) :
In this example, the main gateway is a LANCOM 1781EF +. Since this device does not have a built-in VDSL modem, dial-up to the Internet should be carried out via the LANCOM 730VA, which was configured as VDSL modem in step 1.
