Description:
In this example, the IAD acts as a bridge which bridging the PC IP addresses from
LAN to WAN. The PC IP address can be a static public address that is pre-assigned
by the ISP or a dynamic public address that is assigned by the ISP DHCP server, or
an IP address received from PPPoE software.
Therefore, it does not require a public IP address. It only has a default private IP
address (192.168.1.1) for management purpose.
Configuration:
1.
Choose a client PC and set the IP as 192.168.1.x (x is between 2 and 254) and
the gateway as 192.168.1.1.
2.
Start your browser and type
192.168.1.1
in the URL box to access ADSL
