Configure a PPPoE Connection

This topic describes how to configure a PPPoE connection on Yeastar P-Series PBX System to obtain an IP address when the PBX is in Dual network mode.

Background information

A PPPoE client assigns a dynamic IP address to the PBX, the IP address of the PBX may vary every time the PBX starts up. In this case, you need to configure dual network, and configure a static IP address on the PBX to ensure that you can always access the PBX.

The following instructions assume that you need to connect LAN port to local network, connect WAN port to PPPoE. The network information is as the following:

LAN WAN
Static IP
  • IP address: 192.168.6.124
  • Gateway address: 192.168.6.1
  • Subnet mask: 255.255.255.0
  • DNS: 192.168.1.1
PPPoE
  • Username: 059219383822
  • Password: 19283772

Procedure

  1. Log in to PBX web portal, go to System > Network > Basic Settings.
  2. In the Basic section, configure the following settings:
    • Ethernet Mode: Select the Ethernet mode. In this scenario, select Dual.
      • Single: Only the LAN port will be used for up-link connection.
      • Dual: Both LAN and WAN can be used for up-link connection.
        Note: The traffic will be routed to the default interface; you may need to add a static route to override the default route entries, routing the traffic from a specific IP address to the specified destination.
      • Bridge: LAN port will be used for up-link connection. WAN port can be used as a bridge to connect other device.
    • Default Interface: Select the port where PPPoE is connected. In the scenario, select WAN.
  3. In the LAN section, select Static IP Address, and enter the network information for LAN port.

    • IP Address: Enter the IP address that is assigned to the PBX.
    • Subnet Mask: Enter the subnet mask.
    • Gateway: Enter the gateway address.
    • Preferred DNS Server: Enter the IP address of preferred DNS server.
    • Alternative DNS Server: Optional. Enter the IP address of alternative DNS server.
    • IP Address 2: Optional. Enter a second IP address for the PBX.
      Note: According to your network environment, you may need to set another IP address to allow users in different IP segment to access the PBX.
    • Subnet Mask 2: Optional. Enter another subnet mask for the second IP address.
  4. In the WAN section, select PPPoE and enter the Username and Password.

  5. Click Save and reboot the PBX to take effect.

Result

Both LAN and WAN are set up for the PBX.

  • All network traffic will be sent and received by the WAN port (default network interface).
  • You can access the PBX web portal by the LAN IP address to configure the PBX settings.

What to do next

If you want to route network traffic through LAN port, you need to add static routes on the PBX. For more information, see Add a Static Route.
