PPP Password: The password assigned by your ISP.
Note: If you set the username/password to default/default, the modem will redirect the
user to a web page within the modem to change their password when they first log on.
PPPoE Service Name: Server name of network ISP. No need to set.
Authentication Method: Authentication mode of network ISP. Default is AUTO
Enable Fullcone NAT: RFC 3489 defines four types of Network Address Translation
(NAT). Fullcone NAT. As with other types of NAT there is a mapping from a public IP
address to a private IP address. The external public IP address is extended with the
external port. With Fullcone NAT once the mapping is created any external host may
send packets to the private IP address by sending to the external IP address and port.
Other types of NAT have restrictions such as the sending IP address must initially have
had packets sent from the private IP address and port regardless of the external port, or
from the private IP address and the external port.
Enable NAT must be checked for Fullcone NAT to be used.
MAC Clone: Clicking the Clone the PC MAC Address button will use the MAC address
from the connected PC for the MAC address of the router.
PPP Dial Up Delay Minutes: The number of minutes the router will pause before
attempting PPP authentication. The default (0) means that the router will pause a random
number of seconds before attempting authentication. This setting helps prevents the PPP
server from being flooded with authentication requests after a power shutdown or a reset.
Dial on demand: When this mode is selected, the connection that has no traffic within
assigned disconnect timeout (e.g. 1 minute) will be automatically disconnected. The
connection will be activated again when traffic arrives. This function is advantageous for
users who are charged with online time. It should be noticed that some programs
automatically link to Internet. Computer will send data to network when infected by virus.
Connection will not be disconnected under these data streams.
Inactivity Timeout: When Dial on demand is selected, this input box indicates that after
how long the connection will be disconnected in the absence of traffic. If the value is 0,
connection will not be disconnected.
Manual Connect: connect/disconnect PPPoE connection manually.
Enable manual MTU set, allows you to set a value for the MTU: the Maximum
transmission unit (MTU). Higher MTU can provide for a more efficient link because each
packet will carry more data while the overhead in the packet such as header information
does not get larger with the size of the packet. So the bulk throughput on the link will go
up. Generally a large packet size can occupy the time on the link, so the higher MTU can
increase lag time and minimum latency which is not appropriate for all applications.
PPP IP extension: Allows only one PC on the LAN. The public IP address assigned by
the remote using the PPP/IPCP protocol is actually not used on the WAN PPP interface.
Instead, it is forwarded to the PC's LAN interface through DHCP.
Only one PC on the LAN can be connected to the remote since the DHCP server within
the ADSL gateway has only a single IP address to assign to a LAN device. NAT and
firewall are disabled when this option is selected. The ADSL gateway becomes the
default gateway and DNS server to the PC through DHCP using the LAN interface IP
address. The ADSL gateway extends the IP subnet at the remote service provider to the
LAN PC. That is, the PC becomes a host belonging to the same IP subnet. The ADSL
gateway bridges the IP packets between WAN and LAN ports, unless the packet is
addressed to the gateway's LAN IP address.
Enable NAT: To define NAT services in the Advanced Setup | NAT screens, NAT must
be enabled.
NAT Public Address (available if NAT is enabled). Automatic means the modem will
use pubic IP addresses provided by the network; Menu IP addresses means that the
modem will use the addresses you specify.
Enable Firewall: Enables the router firewall.
Use Static IPv4 Address: Defines a static IP address (v4) which you enter in the IPv4
