In the Wide Area Network (WAN) Service Setup page, you will see the new WAN interface
added.
Add a PPPoA WAN Service
1.
Add a PPPoA Layer 2 interface as described above (Add a Layer 2 Interface).
2.
Under Advanced Setup click WAN Service then click Add
3.
On the WAN Service Interface Configuration page, select the DSL link associated with the
PPOA interface from the drop down, then click Next
4.
On the WAN Service Configuration page, enter a name if you wish to customize the
description shown for the service, then click Next.

On the PPP Username and Password page you will need to enter information provided by
your ISP. When you are done, click Next.
PPP Username
: Your account from ISP to access Internet.
PPP Password
: The password assigned by your ISP.
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.
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.
Enable manual MTU set
: the Maximum transmission unit (MTU) value may be set for
your needs. 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.
Manual Connect
: connect/disconnect PPPoE connection manually.
Enable NAT
: To define NAT services in the
Advanced Setup | NAT
screens, NAT must
be enabled.
Enable Firewall
: Enables Firewall.
Use Static IPv4 Address
: Defines a static IP address (v4) which you enter in the
IPv4
Address
text box which is displayed when the
Use Static IPv4 Address
check box is
selected.
Enable PPP Debug Mode
: Used to debug PPPoA issues. Use only when instructed by
your ISP.
