P-660RU-T v2 User’s Guide

The following lists out the steps taken, when a computer tries to access the Internet for the first 
time through the ZyXEL Device.

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 ZyXEL Device) 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 ZyXEL Device 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 ZyXEL 
Device. 

5 When the ZyXEL Device 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 ZyXEL Device and 
the Internet as if it is in the same subnet as the ZyXEL Device.
