Applies to the following xDSL Modem/Routers – is applicable for DSL-N55U (both Annex A and Annex B), DSL-AC68U, DSL-N66U, DSL-N17U, DSL-AC56U, DSL-AC52U, DSL-N16, DSL-N55U_D1, DSL-N55U_C1, DSL-N16U, DSL-N14U, DSL-N12U_C1, DSL-N12E_C1, and DSL_N10_C1.
Enable PPPoE relay:
PPPoE stands for Point-to-Point Protocol over Ethernet, a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It is used mainly with DSL services where individual users connect to a DSL modem over Ethernet.
PPPoE Relay enables the ASUS device (Modem/Router) to allow other devices to connect directly to the PPPoE connection and obtain the IP Address, most ISP (residential) are only allocated one IP address per DSL connection, if more than one PPPoE connected device is required, then additional IP addresses have to be requested from DSL service provider (ISP).
To Configure ASUS PPPoE Relay:
In WAN – NAT Passthrough page, you can see “Enable PPPoE Relay” option. Set it to “Enable” and press “Apply” button.
Now go to your LAN client, and try to connect with your PPPoE account/password, you will get a public IP and connectivity
