4.2.2 DHCP Mode
Select WAN Setup in the Basic Menu. Then select DHCP mode (the host obtains an IP address
from the ISP automatically via DHCP protocol) and click on Next. The following screen is
displayed. Click on Yes.
4.2.3 PPPoE
PPPoE provides session authentication using either Password Authentication Protocol (PAP) or
Challenge Handshake Authentication Protocol (CHAP). Session accounting is possible and
conservation of bandwidth can be achieved by closing down unused sessions. By utilizing PPP,
link and network parameters are easily negotiated between the Gateway and the ISP.
When using PPPoE, the system is assigned an IP address from the Internet Service Provider as
part of establishing the network connection. The system can be configured as a DHCP server for
the LAN, and NAT can be used to translate private addresses to public addresses. In this way,
computers in the LAN do not have to have their own public IP addresses.
To set up PPPoE, select WAN Setup in the Basic Menu.
Enter your user name and password (as assigned by your ISP) and click on Apply.
