DG834 ROUTER FOR USE WITH THE VXM4
DG834 ROUTER FOR USE WITH THE VXM4
REQUIREMENTS
1. Netgear DG834 router
2. A Laptop or PC to configure the DG834
3. An Internet connection and all required login details (username and password provided by your ISP)
SETUP STEPS FOR INTERNET CONNECTION
1. The DG834 has a default IP address of 192.168.0.1, so configure your laptop or PC with an IP address of 192.168.0.2 and gateway of
192.168.0.1 and connect to the DG834 using the standard CAT-5 patch lead supplied with the router.
2. Open Internet Explorer and enter http://192.168.0.1 to connect to the router. When prompted, enter user name of ‘admin’ and password ‘password’
3. If the DG834 has never been setup before, it will prompt whether you wish to use the setup wizard – do not do this.
4. Choose ‘Basic Settings’ from the menu on the left. Select yes for ‘Does your internet connection require a login’ and enter your username and
password as provided by your ISP. Other information required on this screen can be left at defaults. Apply these settings and then verify that you
now have internet access from the PC / Laptop
SETUP STEPS FOR CONNECTING A VXM4 LOCALLY
1. Configure the VXM4 (refer to page 18 for details) so that it has a unique IP address which is in the same range as the router and PC/laptop. For
example, in this case choose 192.168.0.3. Set the gateway IP on the DVR to the router’s IP address of 192.168.0.1. Note that the default port
number is 6100.
2. Connect the VXM4 to the router using a standard CAT-5 patch lead and verify that it can be ‘pinged’ from the PC as follows
a) Open a command prompt with the following sequence: START – RUN – type in ‘CMD’ – OK
b) At the command prompt, type ‘PING 192.168.0.3’. If you see 4 lines saying ‘reply from 192.168.0.3: ………..’ then the VXM4 is recognised on
the local network. If not, work through the above steps again, but also check that the CAT-5 patch lead is OK.
3. At this point, the connection to the VXM4 can be tested locally. Install the remote agent software (page 27) and follow the steps to create a
connection group, entering IP address, username and password for the VXM4 and port number as noted in step 1 above. The remote agent should
successfully connect to the VXM4 allowing you to view images remotely on the PC/laptop
SETUP STEPS TO ALLOW REMOTE VIEWING OVER BROADBAND
BASIC PRINCIPLES
Imagine the Netgear DG834 is split in to two halves - one half is the private side which serves the local network. This ‘half’ of the router has its own
IP address (typically 192.168.0.1) and other devices (PCs, laptops, VXM4 etc.) that are connected to it will all have a unique IP address of the form
192.168.0.XXX.
Because this is a private network, it cannot be accessed directly from the outside world.
The other imaginary half of the DG834G is the public side - it also has its own IP address which is allocated to you by your ISP and can either be
static (it never changes) or dynamic (your ISP could change it at any time). Because this is a public network, in theory, anyone from the outside world
who knows your public IP address can access the router and your private network. But, because the router has a security firewall built in, incoming
traffic is severely limited to prevent this.
For this reason, you need to configure the DG834 so that incoming traffic intended for the VXM4 is correctly routed instead of being blocked - this
is known as port forwarding.
You will notice on the VXM4 that in the network setup section, there is also a port number. This could technically be any value but you must avoid
common Internet ports such as 80, 110, 25, 21 etc. In general, the default value on the VXM4 is acceptable.
In this case, the VXM4 default port value is 6100 so a rule needs creating on the DG834 that channels all traffic coming in on port 6100 to the VXM4
