ZyXEL P-330W User's Guide Table 34 Advanced: WAN DHCP IP Encapsulation LABEL DESCRIPTION Enable UPnP UPnP (Universal Plug and Play) allows automatic discovery and configuration of the Wireless Router. UPnP is by supported by Windows ME, XP, or later. Put a check in this box to allow the router configuration to be changed by UPnP devices. IPSec Passthrough Put a check in this box to enable computers on your LAN to make IPSec VPN connections to servers on the Internet. PPTP Passthrough Put a check in this box to enable computers on your LAN to make PPTP VPN connections to servers on the Internet. L2TP Passthrough Put a check in this box to enable computers on your LAN to make L2TP VPN connections to servers on the Internet. Save Click Save to save your changes back to the P-330W. Reset Click Reset to begin configuring this screen afresh. 6.7.3 PPPoE Encapsulation The P-330W supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft 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 dialup connection using PPPoE. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius). PPPoE provides a login and authentication method that the existing Microsoft Dial-Up Networking software can activate, and therefore requires no new learning or procedures for Windows users. 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 P-330W (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the P-330W does that part of the task. Furthermore, with NAT, all of the LANs' computers will have access. The screen shown next is for PPPoE encapsulation. Chapter 6 Advanced Options 80
