Router Bridging With Draytek Vigor 130
- A Simple Guide To Establishing A Connection
[Draytek Vigor 2830n // Draytek Vigor 130 for VDSL to ADSL client]
The guides on how to use a router bridge, namely a Draytek Vigor 130, to connect an ADSL client to VDSL are not very clear or, more accurately in most cases, downright misleading. This is a simple guide on how to connect an ADSL router to a brige device for VDSL internet.
- Draytek Vigor 130
- router connected to bridge unit by ethernet cable, from WAN2 port (if present) to brige ethernet port
- telephone / broadband service line connected to the bridge
- computer or laptop ethernet cable connected to the router
- Draytek Vigor 2830n
- Reset the bridge device and connect via 192.168.2.1 (not the default 192.168.1.1 for most Draytek routers)
- in General Setup ensure that ADSL service is disabled, and that both the 101 VLAN tag and the VDSL service are enabled, with VDSL2 only in the top drop-down menu*
- configure the bridge as a PPoA/PPoE device by enabling that service (no further configuration for PPoA/PPoE required)
- Set the current PPoA/PPoE tab option on the router side to disabled, set the VLAN tag to 101 for WAN2 (WAN > General Setup > WAN2 and click on the actual WAN2 word) and then configure WAN2 for PPoE, adding the ISP login credentials in the process to the PPoE configuration [WAN alias details (if any) can be added to the PPoE configuration, too].
- allow the router to reboot, ensuring that the router is connected to the bridge device via the WAN2 or PPoE port and that the PPoE connection is active; also that the PPoE connection is the only connection and that the MTU is set to 1492
That's it: if all has gone as it should then you should have now have a PPoE connection from the router to the bridge, and internet access from an ADSL client via a VDSL bridge device.
The Draytek Vigor 130 bridge supports both IPv4 and IPv6, but the service speed may be affected by networking speed limitations on the router side in the case of high-speed fibre internet services. It should also be noted that using a bridge will make the connection slightly laggy and not as smooth or consistent as it would be using a VDSL router and no bridge.
Most browsers, especially Firefox, do not work well with the configuration interface for this device and will frequently time-out or fail to connect, so it can be helpful to:
Note to the pedantic:
- disable auto-logout (at least during the configuration process)
- keep the interface open in the browser until everything has been configured
- remember that the Vigor 130 bridge device is extremely slow to reset and refresh, so allow at least a couple of minutes after each reboot before attempting further interaction with the interface.
- try to configure everything all in one go (there is very little that is configurable) to avoid the frustration of repeatedly having to reset the bridge device in order to access it.
- it is highly unlikely that the bridge device will be accessible via the router (the slow response times of the unit normally cause connection attempts to fail, so configuring it is usually best via a direct connection to the ethernet port on the PC or laptop).
this method of bridging is actually called PPoE-Passthrough and is not true bridging which, as I understand it, would require the use of the MPoA alternative method.
*ADSL service will not run over VDSL and vice-versa, ie: it is not possible to have ADSL or VDSL fallback on the same service line outside of service provider reversions.
