* With the HG612 powered off, connect a cable between the LAN2 port
(you may need to remove the "not in use" sticker) and the ethernet
port on your computer.
* Configure your computer's ethernet port with the IP address
192.168.1.100 and subnet mask 255.255.255.0.
* Hold down the reset button on the back of the HG612 whilst inserting
the power cable. Keep the rest button held for about 5-10 seconds
after powering up.
* After about 10 seconds you should be able to access the HG612's
"Update Software" web page at the address http://192.168.1.1
* Follow the on-screen instructions to upload the latest firmware.
* Change the HG612's IP address (under "Basic -> LAN" in the web
interface) to be an unused address on your LAN. e.g. if your LAN is
192.168.1.0/24, with your router using 192.168.1.1 you could change
the HG612 to use 192.168.1.2.
* Connect a cable between the LAN2 port on the HG612 and your LAN
switch (or an unused LAN port on your router).
* You should now be able to access the HG612 from any device on your
LAN by visiting http://192.168.1.2
A more elegant solution is to enable access to the HG612 over the
* In your router, configure the WAN interface with a private (RFC1918)
address in a different subnet to your main LAN. e.g. if your main
LAN is 192.168.1.0/24 then configure the WAN interface with the
address 192.168.2.1/24
* Change the HG612's IP address (under "Basic -> "LAN" in the web
interface) to be any address in that second subnet -
e.g. 192.168.2.2/24
* Under "Basic -> WAN" on the HG612, ensure both "Port binding:"
checkboxes are unticked and press the Submit button to save the
change. This step enables LAN access via LAN1.
* At this point, your router knows where to send packets from devices
on your main LAN to the HG612, but the HG612 doesn't know where to
route responses (it can't be configured to have a default route via
your router).
To fix this, we need to add a static route ("Advanced -> Routing" in
the HG612's web interface) from the HG612 back to your main LAN.
e.g. if your LAN is 192.168.1.0/24 and the router's WAN interface is
192.168.2.1 then you would create the following route:
Destination network address: 192.168.1.0
