EWAN
In EWAN mode, LAN 1 port will be configured as EWAN port for connecting to Internet.
Protocol: You can select one of four protocols for the router's WAN settings: Obtain
an IP Address Automatically, Fixed IP Address, PPPoE, Pure Bridge.
1. Obtain an IP Address Automatically: Select this item if the device is connected to a
router that has DHCP functionality enabled.
NAT: The NAT (Network Address Translation) feature allows multiple users to access the
Internet through a single IP account, sharing the single IP address. If PCs in LAN should share
the WAN IP for WAN access, please enable NAT. If users on your LAN have public IP
addresses and can access the Internet directly, the NAT function can be disabled.
MAC Spoofing: Select Enable and enter a MAC address that will temporarily change your
router's MAC address to the one you have specified in this field. Leave it as Disabled if you do
not wish to change the MAC address of your router.
Obtain DNS: Check the Automatic to enable the router to configure this value, or type in the
Primary and Secondary DNS values provided by your ISP.
