LABEL DESCRIPTION
PPPoE This field is available when you select PPPoE encapsulation.
Passthrough
In addition to the VMG'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 VMG. 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.
IP Address (This is available only when you select IPv4 Only or IPv4 IPv6 DualStack in the IPv4/IPv6 Mode field.)
Obtain an IP A static IP address is a fixed IP that your ISP gives you. A dynamic IP address is not fixed; the ISP
Address assigns you a different one each time you connect to the Internet. Select this if you have a
Automatically dynamic IP address.
Static IP Address Select this option If the ISP assigned a fixed IP address.
IP Address Enter the static IP address provided by your ISP.
VLAN (These fields appear when the Type is set to ADSL/VDSL over PTM.)
Active Select this to enable VLAN on this WAN interface.
802.1p IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame that
contains bits to define class of service.
Select the IEEE 802.1p priority level (from 0 to 7) to add to traffic through this connection. The
greater the number, the higher the priority level.
802.1q Type the VLAN ID number (from 1 to 4094) for traffic through this connection.
MTU
MTU Enter the MTU (Maximum Transfer Unit) size for this traffic.
Routing Feature (This is available only when you select IPv4 Only or IPv4 IPv6 DualStack in the IPv4/IPv6 Mode field.)
NAT Enable Select this option to activate NAT on this connection.
Fullcone NAT Select this option to enable full cone NAT on this connection. This field is available only when you
Enable activate NAT. In full cone NAT, the VMG maps all outgoing packets from an internal IP address
and port to a single IP address and port on the external network. The VMG also maps packets
coming to that external IP address and port to the internal IP address and port.
IGMP Proxy Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish
Enable membership in a Multicast group - it is not used to carry user data.
Select this option to have the VMG act as an IGMP proxy on this connection. This allows the VMG
to get subscribing information and maintain a joined member list for each multicast group. It can
reduce multicast traffic significantly.
Apply as Default Select this option to have the VMG use the WAN interface of this connection as the system
Gateway default gateway.
DNS Server (This is available only when you select IPv4 Only or IPv4 IPv6 DualStack in the IPv4/IPv6 Mode field.)
Select Obtain DNS Info Automically if you want the VMG to use the DNS server addresses
assigned by your ISP.
Select Use Following Static DNS Address if you want the VMG to use the DNS server addresses
you configure manually.
Primary DNS Enter the first DNS server address assigned by the ISP.
Server
Secondary DNS Enter the second DNS server address assigned by the ISP.
