Logical steps...
Update Netgear Firmware to latest version.
As Mr Meowski said, somewhere in advanced settings will be a new
option to switch Router to Modem mode.
Draytek is up-to-date (they stopped making new firmware years
ago).
Go back to the Easy Setup Wizard that I talked you through
earlier today and change DHCP to PPPoE.
And that is it really..
.. Unless you plan on using uPNP (which I suggest you don't) or
plan to run an Internet facing server. There is no harm
what-so-ever in sitting behind the two NAT's.
You can turn off uPNP on the Draytek (Mr Meowski mentioned how
bad that stuff is for security a few years ago).
I do agree with Giles however and setting it up properly would
make things more predictable and centralised later on down the
road.

Hi Giles
Thanks for the explanation. It doesn't have a modem and
therefore cannot handle ADSL. If I switch the Netgear into Modem
mode, will that stop the Draytek from working please? I am
trying to put this into logical steps. Thanks

Hi
Thanks for all the replies thus far. My goal today was to
install the hardware and make it work which it is now doing.
Thus far I have switched off wifi on the Netgear and it is now
cabling into the Draytek which is providing wifi around the
house. It is nice having numerous device connected and no lag!
So, it would be easy for me to sit back and admire what has
been accomplished but I believe some might suggest to do more!
Can I have a vote please? Safest option is to leave it be but
I am already aware of the router's power capability. So leave
be or switch Netgear into modem mode and then configure the
Draytek to do all the work. I must admit that I am tending
towards that. It means the Draytek could be left on if or when
we get cable or fibre. It would be an easy install.
Can Giles explain a bit more about PPPoE please?
So at the moment you are in a situation where your clients
obtain an IP Address from the Draytek, which translates it to
the Draytek IP address and passes the traffic to the Netgear
which translates it to the address on your ADSL line. This
multiple number of translations adds a certain amount of
unnecessary transitions and could hinder certain types of
network access (protocols relying on uPNP might not work, and
set up of remote access connections inbound from the Internet
would be more involved).
By turning your Netgear into modem mode it will use a process
called PPP or PPPoA (PPP over ATM, which ADSL uses) to connect
to the WAN port (your ISP provider). In modem mode you can pass
this process username, password, VPI, VCI, directly over to
PPPoE (PPP over Ethernet). It essentially means that the the
Netgear ceases to be a router (at the moment it is still
routing), and the Draytek will get a real-world IP address,
meaning that there are fewer NAT translations for your access to
the Internet, the Netgear becomes a simpler device and you can
concentrate on doing everything on the Draytek.
As you say, you have everything working, so if it isn't causing
an issue for you then you can continue as you are, but the
Netgear in modem mode --> Draytek Firewall would be a
superior (in my opinion) set up. No hurry if you're not
experiencing a problem.
I'm not as familiar with Draytek kit as some might have been
assuming, I'm using a BT Openreach modem, and have a Cisco ASA
running PPPoE to that, then a small world reachable static
subnet and another Cisco ASA which fronts my home/small business
network(s). So I have some idea about the PPPoE setup, but not
specific to Draytek (I am interested in Draytek though, so if
anyone has any hardware?)
Does the Draytek have an ADSL interface, just wondering whether
it can do everything and then you can completely lose the
Netgear?
