Chapter 10 WAN The following table describes the labels in this screen. Table 27 Network > WAN > Internet Connection: PPPoE Encapsulation LABEL DESCRIPTION ISP Parameters for Internet Access Encapsulation Select PPPoE if you connect to your Internet via dial-up. IPv4 / IPv6 Select IPv4 Only if you want the NBG6616 to run IPv4 only. Select Dual Stack to allow the NBG6616 to run IPv4 and IPv6 at the same time. Select IPv6 Only if you want the NBG6616 to run IPv6 only. PPP Information PPP Username Type the user name given to you by your ISP. PPP Password Type the password associated with the user name above. MTU Size Enter the Maximum Transmission Unit (MTU) or the largest packet size per frame that your NBG6616 can receive and process. PPP Auto Connect Select this option if you do not want the connection to time out. Idle Timeout (second) This value specifies the time in minutes that elapses before the router automatically disconnects from the PPPoE server. PPPoE Service Name Enter the PPPoE service name specified in the ISP account. WAN IP Address Assignment Get automatically Select this option If your ISP did not assign you a fixed IP address. This is the default from ISP selection. Use Fixed IP Address Select this option If the ISP assigned a fixed IP address. My WAN IP Address Enter your WAN IP address in this field if you selected Use Fixed IP Address. 6RD Use IPv6 Rapid Deployment (6rd) when the local network uses IPv6 and the ISP has an IPv4 network. When the NBG6616 has an IPv4 WAN address and you set IPv6/IPv4 mode to IPv4 Only, you can enable 6rd to encapsulate IPv6 packets in IPv4 packets to cross the ISP's IPv4 network. The NBG6616 generates a global IPv6 prefix from its IPv4 WAN address and tunnels IPv6 traffic to the ISP's Border Relay router to connect to the native IPv6 Internet. The local network can also use IPv4 services. The NBG6616 uses its configured IPv4 WAN IP to route IPv4 traffic to the IPv4 Internet. This is available only when you select IPv4 Only in the IPv6/IPv4 field. Enable 6RD Enable IPv6 rapid deployment to tunnel IPv6 traffic from the local network through the ISP's IPv4 network. Automatically configured by DHCPC Select this to have the NBG6616 detect the relay server's IP address automatically through DHCP. Manually Configured Select this if you have the IPv4 address of the relay server. Border Relay IPv4 Specify the relay server's IPv4 address. Address Service Provider IPv6 Prefix Enter an IPv6 prefix for tunneling IPv6 traffic to the ISP's Border Relay router and connecting to the native IPv6 Internet. Service Provider IPv6 Prefix length Enter the IPv6 prefix length. An IPv6 prefix length specifies how many most significant bits (starting from the left) in the address compose the network address. IPv4 mask length Enter the subnet mask number (1~32) for the IPv4 network. NBG6616 User's Guide 81
