Ɣ Nat: Select it to enable the NAT proxy ARP on the WAN interface.
 Mode: It specifies the speed and duplex mode of the WAN interface. The Device
supports five or six modes (Note that only the gigabit WAN interface supports
1000M-HD), which include Auto (Auto-negotiation), 100M-FD (100M Full-Duplex),
100M-HD (100M Half-Duplex), 10M-FD (10M Full-Duplex), and 10M-HD (10M
Half-Duplex) , 1000M-FD (1000M Full-Duplex). In most cases, please leave the
default value. If a compatibility problem occurred, or the network device connected to
the WAN interface doesn¶t support auto-negotiation function, you may modify it as
required.
 MAC Address: It specifies the MAC address of the WAN interface. In most cases,
please leave the default value.
¾ Save: Click it to save the PPPoE Internet connection settings.
Note
1. The Dial Sub-interface can only be configured on the product that supports the IEEE
802.1Q tag-based VLAN feature. If you create multiple PPPoE Internet connections
on a WAN Interface, some ISPs may forbid these connections to access their
broadband access servers as they are using the same MAC address (that is, the
WAN Interface¶s MAC address). You can use sub-interface feature to solve this
problem: connect the WAN1 to a switch that provides 802.1Q tag-based VLAN
feature, and then create multiple VALN sub-interfaces on the WAN1, lastly create a
connection on each sub-interface respectively; then each connection will use a MAC
address respectively
2. Compared with the PPPoE Internet connection setup page in the Quick Wizard, this
page provides more configuration parameters, such as, Dial Schedule, Online
Schedule, Keepalive Period, Priority, Down Priority, and so on.
3. In most cases, please leave the Proxy ARP the default value, that is, disable the
proxy ARP on the interface. But in some cases, you need enable the proxy ARP. For
example, when you enable PPTP or L2TP server feature on a WAN interface, and the
IP addresses assigned to the mobile user clients are on the same subnet as the
Device LAN interface, you need enable proxy ARP on this interface. Another example
is that when using multi-NAT (that is, you get multiple public IP addresses from your
ISP) on a WAN interface, you should enable NAT proxy ARP on this interface.
