Basic Network Overview

Before using the Yeastar K2 IPPBX in your network, you must configure the basic network.

Network interfaces

Yeastar K2 IPPBX supports LAN interface and WAN interface. By default, the LAN interface is enabled, and the WAN interface is disabled.

According to your network environment, you may need to use dual network interfaces.

If you use dual network interface, the system route entries are automatically created for the default network interface. To properly route the network traffic through the desired network interface, you need to add a static route on the PBX.

Ethernet modes

Yeastar K2 IPPBX supports two Ethernet modes:
  • Single: Only LAN port will be used for connection, WAN port is disabled.
  • Dual: Both LAN port and WAN port can be used for connection.
    If you use Dual mode, you need to choose a default network interface for the PBX.
    Note: The traffic will be routed to the default interface; you need to add a static route to override the default route entries, routing the traffic from a specific IP address to the specified destination.

IP address assignment

Yeastar K2 IPPBX supports three types of IP address assignment:
  • Assign a static IP address

    Contact your network administrator to assign an IP address to the PBX. Then you need to manually configure settings such as the IP address, subnet mask, default gateway, and DNS servers on the PBX.

  • Obtain an IP address from a DHCP server

    You can configure the PBX to automatically obtain its IP address when it starts up from a DHCP server running in your network.

    Note: The IP address assigned to the PBX may vary every time the PBX is started up.
  • Obtain an IP address from a PPPoE client

    You can connect the PBX to a PPPoE client, and set up a PPPoE connection on the PBX to get the IP address.
