3.2 WAN Interface Configuration
The router supports 16 ATM interfaces. A virtual channel (VC) can be configured for each ATM interface
such as ATM1 to VC1, ATM 2 to VC2, and so on. Each VC can be specified with a protocol, which can be
RFC 1483 bridged, RFC 1483 Routed, PPPoE, or PPPoA.
By default, VC1 is enabled with the parameters VPI/VCI 0/33 and protocol RFC 1483 Bridged. VC1 can
work without any modifications. VCs 2 to 16 are disabled.
If the VC is added on the Basic> Wan Setup, it will be added from VC2 to VC16. (VC1 is already enabled
for 0/33).
If a PPPoE-based VC is created on Basic>WAN Setup, the DHCP server will be automatically enabled. If
a PPPoE based VC is created on Advanced>Interface, the DHCP server function must be enabled
manually.
The WAN interface can be configured to operate in the following modes: bridge, router, PPPoE, or
PPPoA. Configuration for each mode is explained in the sections that follow.
