On the DG834, confi gure a service on ports 6201 and 1030 and fi rewall rules to direct these services to 192.168.0.4
The remote client software can then be confi gured with one connection group containing two VXH960 connections to match the above
and then both VXH960s can be accessed remotely at the same time.
Note: If connecting locally over a LAN, the unique 192.168.0.XXX IP address for each VXH960 has to be entered. If connecting over
broadband, the same public IP address is entered for both VXH960s – port forwarding on the router takes care of the rest.
Using DDNS to connect
DDNS (Dynamic Domain Name Server) is generally used when your ISP provides you with a dynamic public IP address. The problem with
a dynamic IP address is that because it can change regularly, any remote users that need to connect to the VXH960 do not know what
IP address to enter in the remote client!
Using DDNS solves this problem. When a VXH960 is correctly confi gured to use DDNS, it regularly interrogates the router and sends the
current public IP address to a 3rd party database. The VXH960 also sends its MAC address, which is unique.
Before using DDNS, the VXH960 must be set up correctly by following the steps on page 39 and verifying that a local connection can be
made.
DDNS - enabled
1st DNS server - must be the local IP address of the router
2nd DNS server - must be the IP address of the ISP’s 2nd DNS server
DDNS server - leave set as DDNS.DVRLINK.NET
Note: if the ISP’s DNS servers are not known, they can be identifi ed as follows:
A) To open a command prompt using Windows XP use the following sequence:
START-RUN - Type in CMD - OK
For Windows Vista / 7 users:
START - Type in CMD -Press Enter
B) At the command prompt, type ‘IPCONFIG /ALL’ and press ENTER. The ISP’s DNS servers are listed at the bottom of the information
screen. If only one server is listed, enter this in the VXH960 1st DNS server, and leave the 2nd DNS server as default
Finally, make a note of the VXH960’s unique MAC address - this can be found in the < SYSTEM SETUP> < SYSTEM > <SYSTEM
INFORMATION> part of the VXH960 setup (page 46).
For example, if the MAC address is 00-11-5F-00-9A-33, the following should be entered instead of an IP address when confi guring a
VXH960 connection group:
00115f009a33.dvrlink.net:6200
Note: the entry should be MAC address.dvrlink.net, not MAC address.ddns.dvrlink.net
When the remote client initiates a connection, it interrogates dvrlink.net for the actual public IP address that corresponds to the MAC
address. It then uses the resulting IP address to connect to the VXH960.
