Enable Fullcone NAT: A full cone 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: After PPP IP extension is enabled, the WAN IP address
obtained by the modem through built-in dial-up can be directly assigned to
the PC being attached with the modem (at this time, the modem has only
one PC). From the view of the PC user, this is even with that the PC dials up
to obtain an IP addres. But actually, the dial-up is done by the modem. If this
function is disabled, the modem itself obtains the WAN IP address
automatically.
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.
IGMP Multicast: IGMP proxy. For example, if you want PPPoE mode to
support IPTV, enable it.
After enter the PPP Username and PPP Password, click Next, and the following
