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
VCI
LLC Encapsulation:
VC Multiplexing:
Enable NAPT
26
Enter a value for the virtual path identifier
Enter a value for the virtual channel identifier
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.
With VC Multiplexing, no link control header is needed as the
ATM Virtual Circuit is assumed to be carrying a single protocol.
Selecting Enabling NAPT will enable Network Port Address
Translation on the WAN interface.
