Description
In this example, the modem is connected to the DSLAM through PVC 8/81 and the
access mode is the RFC2684 (bridged) +NAT. The down link port of DSLAM is
encapsulated in 1483B. The IP address is 20.1.1.1. The IP address of the uplink
port is 10.61.92.157. The WAN IP address of the modem is assigned as 20.1.1.112
and the gateway is 20.1.1.1. The PC to the modem is assigned with a private IP
address (in the same segment as the management IP address 192.168.1.1). The
NAT function of the modem is enabled and the private address of the PC is
translated to the public address of 20.1.1.112 for accessing the ISP. The IP address
of the PC can be fixed (as in this example) or assigned through DHCP server of the
modem. If it is assigned by DHCP server, the DHCP function of the modem must
be enabled. The IP address of the DHCP address pool is 192.168.1.* (2~254). The
functions are enabled by default and the PC is configured to obtain IP and DNS
addresses dynamically.
