Configuring Internet Access for a Network
Overview
Options for Connecting a Network to the Internet Configuring Internet Access by Using a Router Configuring e Web server sends a reply to the computer running NAT
4. The computer running NAT determines the destination, changes the packet header, and sends the packet to the client
IP = 192.168.1.3
Internet
IP = 192.168.1.4 IP = 192.168.1.5
Web Server
IP = 131.107.50.1
1. The client sends the packet to the computer running NAT
2. The computer running NAT changes the packet header and sends the packet over the Internet to the Web server
