Draytek 2710

To set it up in bridge mode

Need to set PPPoE client to Enabled, set PPPoE Passthrough to LAN (tick box “PPPoE Pass-through = For Wired LAN”), and leave all other settings (eg auth) alone. But you may still need to set VCI/VPI etc.

Same for Draytek Vigor120

Note the 120 (and possibly others) on a Mac plugged straight into the USB ethernet adapter will continuously drop the link, looking like it's broken. But it's just having trouble with the auto negotiation maybe. Fix is to plug in into a switch while configuring

Default username / pass is: admin / blank

Cabling for Billions in bridge mode

The most simple method of connecting this up:

1 - connect to the router's WAN port

2 - connect to the network switch

3 - unused

4 - unused

Connecting port 2 to the network switch means that you can still remote into the bridge-mode router for maintenance purposes. Just set your laptop to a static IP address on the 192.168.1.0 range and browse to http://192.168.1.254

Technically, if you wanted to, you could use the Billion bridge-mode router to provide two more switch ports, like so:

1 - connect to the router's WAN port

2 - connect to the router's LAN port

3 - can be used as a general switch port

4 - can be used as a general switch port

In my tests, DHCP on the Billion was disabled when the router was put into bridge-mode using the above instructions. This is good as you want your router or server to be doing DHCP.

When operating correctly, there should be a solid green light in: Power, Ethernet 1, Wireless (although not important), and DSL

The Internet light will remain unlit in bridge mode.

Billion 7404VGP-M

When operating correctly, there should be a solid green light in: PWR, SYS, LAN 1, WLAN (although not important), and ADSL/PPP (one light)

The ADSL light will be solid even if the connected router isn't working. This just means it has line sync.

LAN 1 will flash with activity.
