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
Vigor 2960
Even if your particular DrayTek model is not listed, these instructions should still apply if your particular model is in the same series.
