Chapter 9 WAN Table 22 Network > WAN > Internet Connection: IPoE Encapsulation (continued) LABEL DESCRIPTION First DNS Server Second DNS Server Third DNS Server Select User-Defined and enter the IPv6 DNS server address assigned by the ISP to have the NBG6818 use the IPv6 DNS server addresses you configure manually. Select None if you do not want to configure DNS servers. If you do not configure a DNS server, you must know the IPv6 address of a computer in order to access it. Apply Click Apply to save your changes back to the NBG6818. Cancel Click Cancel to begin configuring this screen afresh. 9.4.2 PPPoE Encapsulation The NBG6818 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection using PPPoE. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius). One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals. Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site. By implementing PPPoE directly on the NBG6818 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6818 does that part of the task. Furthermore, with NAT, all of the LANs' computers will have access. NBG6818 User's Guide 82
