DVR and Router Setup FAQ
We will set up a router, using the Linksys BEFSR41 router. Other routers may also be used.

The DVR we will use is the DVR-8004G. Other DVR's may be used.
Connect the power adapter to the router.

Connect an RJ45 cable between the router's uplink port and your internet source (dsl modem, cable modem, other router). The uplink port on the Linksys is labelled 'Internet'.

Other routers may be label the uplink port differently, or use the highest numbered port.
Connect an RJ45 cable between the router port and the computer (port 1 in orange).

Connect an RJ45 cable between the router port and the DVR (port 2 in white).
On the PC, go to Start->Run->ipconfig
Click 'ok'.

Make a note of the three addresses listed (IP/subnet/gateway).
Power on the DVR. Enter the menu system.

Select network settings.
Set the IP address to be the same as the PC except for the last three digits.
Make the last three digits unique. Write down the IP address of the DVR.

Set the subnet make to be the same as on the PC.

Set the gateway to the same as on the PC.

If there is an option for port number, make a note of it.
You may now access the DVR from the computer.

In a web browser, enter the IP address of the DVR.

If you wish to access the DVR from outside your home network, instructions are listed below.
You may wish to access the DVR remotely (from outside your home network).

To do so, Port Forwarding needs to be set up.

Open an internet browser.

Type in the default IP address for the router. Here, it is
Other routers may use a different IP address

A login box will come up.
Enter the default name and password. Here, it is "admin" and "admin".
Other routers may use a different login, please check the manual.

On the router, go to the menu for port forwarding. Here, we go to Applications->Port Range Forwarding.

Set the port to "80" (or whatever port the DVR had listed), and the IP address to the DVR's. Select 'Enabled'.
Click "Save Changes". The router will restart.

You may now view the DVR from the outside by typing in the IP address of your home network (assigned by the Internet Service Provider. You can check here to find out).
If our IP address at home is 500.500.500.3, then you would type in "http://500.500.500.3" at the remote computer to get to the DVR.

Note: If you set a custom port on the DVR other than 80 (used by web browsers automatically), go to the web browser and type in the port number at the end of the IP address: "http://500.500.500.3:79" if you had set the DVR to use port 79 on the network. This allows web browsers to go to a port other than 80. Make sure the router's port forwarding list matches the custom port number you had specified on the DVR.
Dynamic DNS - you can set up a fixed web address for accessing the DVR, even if your IP address changes. A free service on www.dyndns.com allows this.
