I. High-Speed Solutions
This information is to help you access high-speed Internet services, such as xDSL, or a cable modem
connection. However, since some high-speed Internet services may provide only one external IP
address that may not be static,, there are several practical issues to consider.
AVAILABLE IP ADDRESS
An ISP (Internet Service Provider) ideally will provide you with several static IP addresses – in
which case you can assign any one of these to your Wireless Network IP Camera to make it fully
accessible over the Internet. However, if your service provider supplies you with only one IP address,
which is often the case, this IP number is normally assigned to your PC,-leaving no connection
available for your Wireless Network IP Camera.
What can you do if your ISP is unable to provide you with an IP number?
There are a number of other options to consider, including:
NAT BOX
Short for Network Address Translator, NAT is an Internet standard that allows a local-area network
(LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external
traffic. A NAT box located where your LAN meets the Internet will handle all of the necessary IP
address translations and provides:
z Internal IP addresses that are unique to your network – with no possibility of conflict with
IP Addresses used by other companies and organizations.
z The possibility of combining multiple ISDN connections into a single Internet connection.
z An effective firewall for hiding internal IP addresses.
NAT Feature in Windows 2000
Utilize the NAT feature in Windows 2000 to allow multiple Ethernet cards in your PC, and you can
then use one of port for the Internet and the other for your internal network. With this solution, you
can let your Wireless Network IP Camera upload image streams to an external Web Server that is
maintained and located with your ISP.
