WAN Setup
Click on WAN Setup from the tool bar and configure the WAN interface for these services:
RFC1483 Bridged, RFC1483 Routed, PPPoE, PPPoA, and MER. The following are the common
settings to set up these services.
• VPI and VCI: These identify the virtual circuit.
• 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
6.5.3. This feature is available for RFC 1483 Routed, PPPoE, PPPoA, and MER.
• Enable DHCP: Enables (if checked) or disables the DHCP server. The DHCP server
dynamically allocates network addresses and delivers configuration parameters to hosts.
DHCP or Dynamic Host Configuration Protocol is explained further in section 6.2. This
feature is available for RFC 1483 Routed, PPPoE, PPPoA, and MER.
