APPENDIX B: CONFIGURING A NETGEAR DG384
ROUTER FOR USE wITH VXH264
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 VXH264 do not know what IP address to enter in the
remote client!
Using DDNS solves this problem. When a VXH264 is correctly configured to use DDNS, it regularly interrogates the router and sends the current
public IP address to a 3rd party database. The VXH264 also sends its MAC address, which is unique.
Before using DDNS, the VXH264 must be set up correctly by following the steps on page 37 and verifying that a local connection can be made.
In addition, the following must be configured in the VXH264 NETWORK setup menu (page 29)
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 identified 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 VXH264 1st DNS server, and leave the 2nd DNS server as default
Finally, make a note of the VXH264 unique MAC address - this can be found in the SYSTEM MANAGEMENT part of the VXH264 setup (page 25).
For example, if the MAC address is 00-11-5F-00-9A-33, the following should be entered instead of an IP address when configuring a VXH264 connection
group:
00115f009a33.dvrlink.net
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 VXH264.
