DrayTek Transitioning Phone Services to the NBN Part 2

Hi Everyone, Darren from DrayTek Australia & NZ. In our last video we discussed replacing the
router that the ISP supplied to connect to the NBN service, if it didn’t do everything
we needed it to, and what to do to retain the existing phone service, which was now
locked to the ISP’s supplied router instead of plugged into the old copper phone line system. In this video I’ll go through the configuration
of the DrayTek router and placing the ISP’s supplied router in the DMZ to continue using
it for the Voice over IP service, so we don’t lose the phone number. So starting with the configuration on the Draytek. In this example I’m using a Hybrid Fibre Coaxial
NBN connection. Assuming you already know your ISP username
and password, the first step is to disconnect the ISP’s router from the HFC modem and plug
the modem into the WAN port of the DrayTek router, which in this example is a DrayTek Vigor2762. The Ethernet WAN port on the DrayTek Vigor2762
is a special port (Port 4) that we can use either as a WAN port to connect to the Internet,
or as a LAN port we can plug one of our PCs or other devices into. Now, to get started, plug a PC into one of
the LAN ports of the DrayTek. Now login to the DrayTek router, and go to
WAN>>General Setup. You’ll need to tick the box to enable WAN
2 if it isn’t already. WAN 2 is our Ethernet WAN port. Now go to “Internet Access”, our NBN ISP uses a PPPoE login in this case,
so we select “PPPoE” from the pulldown menu. Then select “Details Page”. We need to enable it, then enter the ISP username
and password. Click ok, and then check the online Status
back on the dashboard page, and we should be online within a few seconds. If you’re not online it could be that your
ISP requires a VLAN tag. I’ll come back to that shortly. One thing we’ll also need to do is change
the LAN subnet of the DrayTek so it doesn’t match the ISP router’s LAN subnet. Technically you could do this on either router
but I had issues getting the routers to see each other when I did that on my ISP’s router
so I recommend changing things on the ISP router as little as possible. So we go to LAN>>General Setup>>Details Page. The default is 192.168.1.”something”. Here’s one I prepared earlier by changing
it to Click ok and it’ll prompt to reboot. Once it does, to log back in you’ll now need
to go to Now we’ll make a few changes to our ISP Router
before we plug it into the DrayTek router. First we’ll unplug our PC from the DrayTek
and plug it into the ISP router, and log in. Most routers use admin/admin by default. Once in, we’ll need to find the settings for
the Ethernet WAN port which in this case in the Advanced section, and down here under
Network called “EWAN”. We want to change it to a static IP and give
it an IP address within the range of the DrayTek router’s LAN subnet which is now 192.168.10.something. Let’s go with The Default Gateway is the Draytek Router’s
IP address which is now And the Primary DNS can be the same unless
you have another DNS server address you prefer such as Google’s. Save that and let it reboot if it prompts to. You might also want to disable the ISP Router’s
Wi-Fi as well if that’s not going to be used. Now we can now go ahead and connect the ISP
Router’s WAN port to one of the DrayTek router LAN ports. Handy Tip: If we leave our PC connected to
the ISP’s router now, we’ll be able to log into either router without having to manually
plug and unplug each time we need to switch. Now to create our DMZ Host for our ISP router
to use, log back into the DrayTek router (remember it’s now on
and go to NAT>>DMZ Host. In this case remember our Internet connection
is on WAN 2, so we select the WAN 2 tab here. Enable it and type in our ISP Router’s IP
address, which we decided would be And click ok. Now, that IP address is inside our DrayTek
router’s DHCP pool. So to prevent a possible IP address conflict from occurring on our network we need to lock it down to ensure no other device can accidentally
grab it. We do that either by changing the DHCP pool
so the address isn’t in it, by changing the start IP address to
for example. The only problem with this method is you’ll
need to now remember you did that if you ever manually assign static IP addresses to any
other devices on your network. A better way is to use the “Bind IP to MAC”
facility down here. All connected devices are displayed in the
ARP table here, so we just select the one we want, which is the ISP router we’ve set
at Click Add. And click ok. Now, that IP address is locked to that MAC
address and nothing else can take it. One other thing we should do is set QoS for VoIP. Go to Bandwidth Management>>Quality of Service
and tick this box under VoIP Prioritization “Enable the First Priority for VoIP SIP/RTP”. And click ok, and reboot if it prompts to. I’ll also just mention here that some VoIP
Service Providers like Telstra also require outbound VoIP packets to be tagged which we
can do down here using the “Add DSCP or Precedence Value” menu option. This ensures the VoIP traffic is prioritised
from end to end in the Telstra network. Without it, Telstra will treat it as normal
data with no particular prioritisation which can result in choppy audio in phone calls. So for this, all we need to do is enable it
for Class 1 and, in the case of Telstra, select “EF Class” from the pulldown menu. Then click ok to save it. If we log back into the ISP router now and go to the dashboard page we should see Internet Status as showing as Connected and also see
that the phone is online. Job done. That’s basically all there is to it. However, one final aspect I mentioned earlier
that we need to address is that many ISPs also use a VLAN tag to authenticate, and we
need to enter that somewhere if we want to get online. Going back to the Vigor2762, let’s assume
we’re with TPG, which uses a VLAN tag of 2 (other ISPs might require a different number). Without that VLAN tag –To enter a VLAN tag on a DrayTek router’s
WAN port, go to WAN>>General Setup. Select WAN 2 in this example for hybrid fibre coaxial, but if you’re using VDSL it would be on WAN 1. Enable VLAN Tag Insertion, and set Tag Value as 2 (or whatever it may be that your ISP uses). Click ok then go back to the Dashboard Page
and voila, now we’re online. Log back into the ISP router and we find it’s
also online. However, if we check the phone status… Uh-oh we have a problem. Now what’s happening here is the security
settings for that VoIP account must also need to see that VLAN tag on this router. To get that happening we need to do two things. First we need to set it on the WAN connection
for the ISP router. So go back Advanced>>Network Settings and
select EWAN again. And all we need to do here is tick “Enable”
for VLAN ID. Enter 2 (or whatever tag your ISP uses) and
save. And then set it on the LAN settings on our
Draytek. Log back into the DrayTek and go to LAN>>VLAN
and click “Enable”. Now for VLAN0, which will be our main local
area network, we’ll tick Port 2 and Port 3. Plus any wireless SSIDs we have. You may notice Port 4 is missing here, and
that’s because Port 4 is configured as our WAN port in this example. Then for VLAN1 we’ll tick the box under Port 1. Enable VLAN tag and enter a VID of 2. And click ok. Now anything plugged into Port 1 will get
a VLAN tag of 2. So we need to make sure the ISP router is
plugged into Port 1 and then log back into it to see if we’ve been successful. We might have to give the ISP Router a reboot
at this point but when it comes back up we should have phone and Internet all working happily. If you don’t, switch both routers and the
NBN Connection Box off, and back on again and it should all come to life. So what we have here now is a VLAN tag of 2 on the WAN port of our Internet-facing DrayTek Router. We have the same VLAN tag on the
dedicated DMZ port. And we have the same VLAN tag on the WAN port
of our ISP’s router behind the DrayTek. Ok, for more detail about this procedure including
a table showing which routers are compatible with each type of NBN, I’ll include a link to our blog article on the same topic in description below. For more information about DrayTek products
