Dm Digital Sprite With Netgear Dg834

You need to setup the DM unit to have a local IP to your router.

Assuming your router / internal network is using the 192.168.0.x range, use a free IP address ie 192.168.0.100

Connect to your routers ip address. If you dont know this connect you laptop / pc to the network and open a command prompt

<Press Start, then click Run, then type CMD>

type ipconfig and press return

you should see

As you can see im using the 192.168.1.x range

The address of my machine is 192.168.1.225

You can usually identify the routers ip by the gateway ip address shown here

in this case its 192.168.1.254

Enter the routers ip address into your browser, ie http://192.168.1.254 (will usually be http://192.168.0.1)

You should then see a screen like

The old DM stuff uses 2 ports. Port 80 (for web access) and Port 8234 (for network viewer access)

The unit should have the software required on the unit itself and this can be downloaded from its internal webpage.

To view this enter the DM units IP address (setup from the DM units Menu) into your browser.

We need to add the required ports to the router so that those ports are forwarded from the router to the DM unit.

From the routers admin pages click on firewall rules

Then click 'Add'' on the inbound services section. The page will change to

Change the 'Service' and select 'HTTP(TCP:80)'

And enter the IP address of the DM unit in the 'Send to LAN server' area

Click 'Apply'

Next click on 'Services' as we need to add the custom port for DM network viewer

Click the 'Add Custom Service' button

in the Name type 'DM' or something to identify this port forwards

Type = TCP

Start Port = 8234

Finish Port = 8234

Click Apply

Then you need to add this forward to the 'firewall rules'

Click Firewall Rules

Then click 'Add'' on the inbound services section. The page will change to

Change the 'Service' and select 'DM(TCP:8234)'

And enter the IP address of the DM unit in the 'Send to LAN server' area

Then Click Apply.

You should now be able to connect to your DM unit externally.

From a browser on a machine NOT on your network enter your public IP address. This is not one of your internal PRIVATE IP address's.

THis should show the web page of the DM unit. Note that some ISP's block port 80. you will have to work around that. This is to prevent you running a webserver on your Broadband and maybe a violation of your terms and conditions. I will make another post if required on how to get around this restriction.

ears. I'll get on that tomorrow.

the above is a good outline tutorial to use as a baseline for many dvrs/routers,

worst issue is to find hen you check from home or the office the access don't work, if your unsure before you leave make the router allow 'remote admin' (get owners permission 1st of course), then if any if any of the settings are wrong within the router, you don't need to actually go back to site to change them.

to get into it, type in the external IP followed by :8080 (default router port) enter the user and password and now you can alter settings as needed, once done and tested for remote access, go back into the router and switch of the 'remote admin' for security needs, then log out of it.

i'd advise here, while i've not tried on a DM unit, on other DVRs i can test remote access settings from a locally connected machine, by entering the sites external IP into the web browser, so worth a go as it won't blow anything up.

I would urge caution to enabling remote access. There has been cases where router DNS entries have been modified to point bank url etc to phising sites.

Im not saying dont but be aware of the risks

Hi there, really interesting post.

I am trying to connect an old DM D4 unit on a homehub 3 and can't seem to get it to work.

I have just read through the explanation above but get stuck where I come to configure the firewall. I am guessing on the HH3 I need to setup the DMZ to forward to the unit but I the unit doesn't show up as a connected device....which is all a little strange. Although I can connect to it through any computer on the network.

Has anyone had success with any of the homehub routers? or any ideas? I'm sure it's something basic I'm doing wrong!

Thanks

Andy

HomeHubs are horrible some hubs provided by ISP's can only "see" a device to forward to, if it has a device name (which most DVR's don't).

There maybe an advanced option to allow you to port forward via IP address not device name, this may not provided in a DMZ.

Check the IP of the unit is static, you know the IP and preferably the IP isn't in the DHCP pool.

Check you can ping the above IP.

Check which port(s) are required by the DVR.

After setting up the port forwarding, test via your External IP from another network.

james how would i get around the port 80 restriction issue, pm me if you dont want joe public knowing .

[james.wilson]

either use a router that con forward from on port to another ie 82 to 80 or change the setting on the unit to use a different port
