Enable Fullcone NAT:. NAT is one where all requests from the same internal

IP address and port are mapped to the same external IP address and port.
Furthermore, any external host can send a packet to the internal host, by
sending a packet to the mapped external address.
Dial on demand (with idle timeout timer): If this function is enabled, you

need to enter the idle timeout time. Within the preset minutes, if the modem
does not detect the flow of the user continuously, the modem automatically
stops the PPPOE connection. Once it detects the flow (like access to a
webpage), the modem restarts the PPPoE dialup. If this function is disabled,
the modem performs PPPoE dial-up all the time. The PPPoE connnection
does not stop, unless the modem is powered off and DSLAM or uplink
equipment is abnormal.
PPP IP extension: If you want to configure DMZ Host, you should enable it

first.
Use Static IPv4 Address: If this function is disabled, the modem obtains an

IP address assigned by an uplink equipment such as BAS, through PPPoE
dial-up. If this function is enabled, the modem uses this IP address as the
WAN IP address.
Enable PPP Debug Mode:Enable or disable this function.

Bridge PPPoE Frames Between WAN and Local Ports:Enable or disable

this function.
Enable IGMP Multicast Proxy:if you want PPPoE mode to support IPTV,

enable it.
