Warning: This will bypass most of the functionality of your DrayTek router, effectively turning it into a simple ADSL modem. It is important that the device plugged into your DrayTek's LAN port is configured to take responsibilty for security.

This is occasionally required, such as when the customer has purchased a specialised firewall device (illustrated below); or where muliple PPPoE logins are required.

internet ISP --- Vigor ADSL Router ---- Firewall appliance ---- switch/hub ---- LAN PCs

In bridged mode, usually only one device should be connected to the DrayTek, and this device will be responsibile for logging in to the ISP (if a PPPoE connection), firewall, IP sharing (aka NAT), etc. If your ISP allows multiple PPPoE logins, then each device connected to the DrayTek must be performing its own PPPoE login.

If using a PPPoE or PPPoa connection from your ISP ...

  1. Please first set DrayTek's Internet Access Setup > PPPoE / PPPoA Client setup page as the following phot
  • Enable the PPPoE/PPPoA Client
  • Set the DSL Modem settings as advised by your ISP
  • Tick the "PPPoE Pass-through for Wired LAN" box. In the very unlikely event that you are using wireless LAN to connect the DrayTek to the next device, tick the "PPPoE Pass-through for Wireless LAN" box.
    Leave all the other fields blank because your firewall on your wired LAN will be doing the PPPoE login.

  2. Then configure the PC / router / firewall device behind the DrayTek to perform PPPoE login (if PPPoe is used).

If using a MPoA connection from your ISP ...

  1. Please first set DrayTek's Internet Access Setup > MPoA page as the following photo:
  • Enable the MPoA Client
  • Set the DSL Modem settings as advised by your ISP
  • Tick the "Enable Bridge Mode" box. Leave all the other fields blank.

Some TPG clients use this configuration, and you can refer to their setup guide.
