I. High Speed Solutions

This information is to help you access high-speed Internet services such as xDSL or a cable modem connection. However, most high-speed Internet Services provide you with some external IP addresses, there are several practical issues that should be considered.

AVAILABLE IP ADDRESS

ISP (Internet Service Provider) will provide you with several external static IP addresses ideally –in which case you can assign any one of these to your NETWORK VIDEO SERVER to make it fully accessible over the Internet. However, if your service provider supplies you with only one IP number – which is often the case – this IP number is normally assigned to your PC-leaving no connection available for your NETWORK VIDEO SERVER.

What can you do if your ISP is unable to provide you with an IP number? There are a number of other options what you may like to consider: including:

NAT BOX

Short for Network Address Translation, NAT (Network Address Translation) is 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:

zInternal IP addresses that are unique to your network – with no possibility of conflict with IP Addresses used by other companies and organizations.

zThe possibility of combining multiple ISDN connections into a single Internet connection.

zAn 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 NETWORK VIDEO SERVER upload image streams to an external Web Server that is maintained and located with your ISP.
