77 Chapter 6 LAN Setup
The following lists out the steps taken, when a computer tries to access the Internet for the first
time through the Prestige.
1 When a computer (which is in a different subnet) first attempts to access the Internet, it
sends packets to its default gateway (which is not the Prestige) by looking at the MAC
address in its ARP table.
2 When the computer cannot locate the default gateway, an ARP request is broadcast on the
LAN.
3 The Prestige receives the ARP request and replies to the computer with its own MAC
address.
4 The computer updates the MAC address for the default gateway to the ARP table. Once
the ARP table is updated, the computer is able to access the Internet through the Prestige.
5 When the Prestige receives packets from the computer, it creates an entry in the IP
routing table so it can properly forward packets intended for the computer.
After all the routing information is updated, the computer can access the Prestige and the
Internet as if it is in the same subnet as the Prestige.
