Internet Connectivity         

Until recently, Microsoft didn’t offer a way for more than one person to share a single connection to the Internet. Linux and Mac OS users have been able to do this for a while, and a number of third parties have shipped products like WinGate. As part of Windows 98 Second Edition, Microsoft included a feature called Internet Connection Sharing, or ICS. The idea behind ICS is simple: If you have more than one computer and they’re networked together, one computer can act as a gateway to the Internet. This is conceptually simple, but there’s some behind-the-scenes magic that has to happen to implement it. ICS actually implements a service called Network Address Translation (NAT). Since every IP packet contains address information, you can probably guess how NAT got its name: It’s a service that translates between your own network’s addresses and addresses usable on the Internet. With either ICS or NAT, your entire network uses only a single IP address on the Internet. All outgoing traffic passes through the NAT machine on its way out. All inbound traffic is likewise addressed to the NAT machine, which is responsible for passing it back to the proper computer on your local network. 

Zebase offers different internet solutions based on the size of the network:

• ICS for small offices and home networks

• NAT for medium and large networks

• Hardware based custom build *NIX gateways for higher security

• Proxy servers with caching capabilities LAN networks with slow internet

• Microsoft Internet Security and Acceleration (ISA) Server 2000

• Cable/DSL routers for small offices and home networks
