Description
In this example, the modem is connected to the DSLAM through PVC 8/81 and the
access mode is the built-in PPPoE+NAT. The encapsulation of the BRAS downlink
port is PPP over Ethernet. The authentication is CHAP PAP. The IP address is
136.1.1.1. The IP pool is 136.1.1.* and the IP address of uplink port is 10.61.92.157.
The IP address of the WAN port on the modem is assigned by BRAS through the
built-in PPPoE dial-up dynamically. The PC that the modem is
to is assigned with
a private IP address (in the same segment as the management IP of the modem).
The NAT function of the modem is enabled and the private PC address is
translated to the public address 136.1.1.* (2 ~ 254) assigned by BRAS dynamically
for access to 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.

After the dial-up is successful, the IP address that the modem obtains at the WAN
side port R_0_32 is 136.1.1.2.
If
Enable NAT
is disabled during the configuration, you must configure the modem
on the BRAS. Otherwise, you can not access your ISP. In actual applications,
Enable NAT
