Setting up SureVoIP Broadband on DrayTek Router

This guide will apply in general to all DrayTek routers with a built-in ADSL modem.

If you have a DrayTek Vigor router supplied by SureVoIP then your router should already be configured and ready to go. Just plug it in when your broadband is live.

It is assumed you require only basic NAT and the ADSL service is your only internet connection. If your requirements require a more complex set up then please contact us for advice.

This guide applies to the following DrayTek models:

  • Vigor 2760
  • Vigor 2762
  • Vigor 2800
  • Vigor 2820
  • Vigor 2830
  • Vigor 2832
  • Vigor 2860
  • Vigor 2862
  • Vigor 2920
  • Vigor 2925
  • Vigor 2952
