3.4.4 PPPoA

When a VC is configured for PPPoA, the router will auto-detect the Authentication code (PAP or CHAP),
and the NAPT function will be enabled automatically.

STEP 1: Click WAN Setup on the Basic menu bar.

STEP 2: Enter values for the following fields: VPI, VCI, Encapsulation (LLC or VC MUX), Enable NAPT.

VPI

Enter a value for the virtual path identifier

VCI

Enter a value for the virtual channel identifier

LLC Encapsulation:

With LLC encapsulation, a link control header is added to the
Ethernet packet that identifies the protocol type (Ethernet). This
allows multiple protocols to be transmitted over the ATM Virtual
Circuit.

VC Multiplexing:

With VC Multiplexing, no link control header is needed as the
ATM Virtual Circuit is assumed to be carrying a single protocol.

Enable NAPT

Selecting Enabling NAPT will enable Network Port Address
Translation on the WAN interface.
