3.5.1.4 (Optional) Configuring NAT

Context
When local area network (LAN) users connect to the device functioning as a PPPoE client on
an IPv4 network, LAN users use private IP addresses. Network Address Translation (NAT)
needs to be configured on the device to translate private IP addresses into public addresses so
that LAN users can access the Internet.

Issue 01 (2014-11-30)
Configure NAT on a dialer interface. For details, see NAT Configuration in the Huawei
AR530&AR550 Series Industrial Switch Routers Configuration Guide: IP Service .
NOTE
When the IP address of the PPPoE client assigned by the PPPoE server is used as the NAT server IP
address, configure the dynamic DNS (DDNS) client. DNS refers to domain name system. For details about
DDNS client configuration, see Configuring the DDNS Client.
In permanent online mode, the device initiates a PPPoE session immediately after the
physical link becomes Up. The PPPoE session persists until you delete it.
In triggered online mode, the device does not initiate a PPPoE session immediately after
the physical link becomes Up. Instead, the device initiates a PPPoE session only when data
needs to be transmitted on the link. If no data is transmitted on the PPPoE link within the
specified period, the device terminates the PPPoE session.
