This topic describes how to restrict users from accessing the web interface of Yeastar K2 IPPBX.

Procedure

  1. Go to Settings > System > Security > Service.
  2. In the Web Access Control drop-down list, set which IP address is allowed to access the PBX.
    • Local Network Only: To allow all the local devices to access the PBX, choose the option.

      The allowed local network segments are as follows:

      • 10.0.0.0/255.0.0.0
      • 172.16.0.0/255.240.0.0
      • 192.168.0.0/255.255.0.0
