4.4 WAN

Setup

Click on WAN Setup from the menu bar to configure the WAN interface for these services:
RFC 1483 Bridged, RFC 1483 Routed, PPPoE, PPPoA, and MER. The following are the common
settings to set up these services.

VPI and VCI

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: NAPT or Network Address Port Translation is explained further in section 5.7.
This feature is available for RFC 1483 Routed, PPPoE, PPPoA, and MER.
