Step 4: In this page, you can modify the PPP username, PPP password, and
authentication method.
PPP Username: The correct user name that your ISP provides to you.
PPP Password: The correct password that your ISP provides to you.
PPPoE Service Name: If your ISP provides it to you, please enter it. If not, do not
enter any information.
Authentication Method: The value can be AUTO, PAP, CHAP, or MSCHAP. Usually,
you can select AUTO.
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.
Advanced DMZ: Only LAN4 port supports this service. This is the virtual server
configuration option. The DMZ Host feature allows one local computer to be exposed
to the internet, to be this feature,the other computer can easily enter the DMZ Host, a
DMZ host is not protected by the firewall and may be vulnerable to attack.
Designating a DMZ host may also put other computers in the home network at risk.
When designating a DMZ host, you must consider the security implications and
protect it if necessary.
PPP IP extension: If you want to configure DMZ Host, you should enable it at first.
Non DMZ IP Address: The DMZ host IP address. You can modify it.
Non DMZ Net Mask: The DMZ Host Subnet Mask, it is build upon the DMZ Host IP
Address.
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 page
