DESCRIPTION
This field is available when you select PPPoE encapsulation.
In addition to the SBG3500-N's built-in PPPoE client, you can enable PPPoE pass through to
allow up to ten hosts on the LAN to use PPPoE client software on their computers to connect
to the ISP via the SBG3500-N. Each host can have a separate account and a public WAN IP
address.
PPPoE pass through is an alternative to NAT for application where NAT is not appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the LAN to use PPPoE client
software on their computers to connect to the ISP.
This is available only when you select IPv4 Only or IPv6/IPv4 DualStack in the IPv6/
IPv4 Mode field.
A static IP address is a fixed IP that your ISP gives you. A dynamic IP address is not fixed;
the ISP assigns you a different one each time you connect to the Internet. Select this if you
have a dynamic IP address.
Select this option if the ISP assigned a fixed IP address.
Enter the static IP address provided by your ISP.
Enter the subnet mask provided by your ISP.
Enter the gateway IP address provided by your ISP.
IPv4 Mode field.
Select this option to activate NAT on this connection.
Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish
membership in a Multicast group - it is not used to carry user data.
Select this option to have the SBG3500-N act as an IGMP proxy on this connection. This
allows the SBG3500-N to get subscribing information and maintain a joined member list for
each multicast group. It can reduce multicast traffic significantly.
Select this option to have the SBG3500-N use the WAN interface of this connection as the
system default gateway.
This is available only when you select IPv4 Only or IPv6/IPv4 DualStack in the IPv6/
IPv4 Mode field.
Select Dynamic if you want the SBG3500-N use the DNS server addresses assigned by your
ISP.
Select Static if you want the SBG3500-N use the DNS server addresses you configure
manually.
Enter the first DNS server address assigned by the ISP.
Enter the second DNS server address assigned by the ISP.
This is available only when you select IPv6/IPv4 DualStack or IPv6 Only in the IPv6/
IPv4 Mode field.
Select Automatic if you want to have the SBG3500-N use the IPv6 prefix from the
connected router's Router Advertisement (RA) to generate an IPv6 address.
Select the Get IPv6 Address From DHCPv6 Server checkbox if you want to obtain an
IPv6 address from a DHCPv6 server. The IP address assigned by a DHCPv6 server has
priority over the IP address automatically generated by the SBG3500-N using the IPv6
prefix from an RA. This option is available only when you choose to get your IPv6 address
automatically.
Select Static if you have a fixed IPv6 address assigned by your ISP.
