Configure the ping responder service

Your Connect EZ 8 device's ping responder service replies to ICMP and ICMPv6 echo requests. The service is enabled by default. You can disable the service, or you can configure the service to use an access control list to limit the service to specified IP address, interfaces, and/or zones.

To enable the iPerf3 server:


  Web

  1. Log into Digi Remote Manager, or log into the local Web UI as a user with full Admin access rights.
  2. Access the device configuration:

    1. Locate your device as described in Use Digi Remote Manager to view and manage your device.
    2. Click the Device ID.
    3. Click Settings.
    4. Click to expand Config.

    1. On the menu, click System. Under Configuration, click Device Configuration.

      The Configuration window is displayed.

  3. Click Services > Ping responder.

    The ping responder service is enabled by default. Click Enable to disable all ping responses.

  4. Click to expand Access control list to restrict ping responses to specified IP address, interfaces, and/or zones:
    • To limit access to specified IPv4 addresses and networks:
      1. Click IPv4 Addresses.
      2. For Add Address, click .
      3. For Address, enter the IPv4 address or network that can access the device's ping responder. Allowed values are:
        • A single IP address or host name.
        • A network designation in CIDR notation, for example, 192.168.1.0/24.
        • any: No limit to IPv4 addresses that can access the ping responder.
      4. Click again to list additional IP addresses or networks.
    • To limit access to specified IPv6 addresses and networks:
      1. Click IPv6 Addresses.
      2. For Add Address, click .
      3. For Address, enter the IPv6 address or network that can access the device's ping responder. Allowed values are:
        • A single IP address or host name.
        • A network designation in CIDR notation, for example, 2001:db8::/48.
        • any: No limit to IPv6 addresses that can access the ping responder.
      4. Click again to list additional IP addresses or networks.
    • To limit access to hosts connected through a specified interface on the device:
      1. Click Interfaces.
      2. For Add Interface, click .
      3. For Interface, select the appropriate interface from the dropdown.
      4. Click again to allow access through additional interfaces.
    • To limit access based on firewall zones:
      1. Click Zones. By default, there are three firewall zones already configured: Internal, Edge, and IPsec.
      2. For Add Zone, click .
      3. For Zone, select the appropriate firewall zone from the dropdown.

        See Firewall configuration for information about firewall zones.

      4. Click again to allow access through additional firewall zones.
  5. Click Apply to save the configuration and apply the change.
  1. Select the device in Remote Manager and click Actions > Open Console, or log into the Connect EZ 8 local command line as a user with full Admin access rights.

    Depending on your device configuration, you may be presented with an Access selection menu. Type admin to access the Admin CLI.

  2. At the command line, type config to enter configuration mode:

    > config
(config)>

  3. Enable the iPerf server:
    (config)> service iperf enable true
(config)>
  4. (Optional) Set the port number for the iPerf server listening port. The default is 5201.
    (config)> service iperf port port_number
(config)>
    • To limit access to specified IPv4 addresses and networks:
      (config)> add service iperf acl address end value
(config)>

      Where value can be:

      • A single IP address or host name.
      • A network designation in CIDR notation, for example, 192.168.1.0/24.
      • any: No limit to IPv4 addresses that can access the service-type.

      Repeat this step to list additional IP addresses or networks.

    • To limit access to specified IPv6 addresses and networks:
      (config)> add service iperf acl address6 end value
(config)>

      Where value can be:

      • A single IP address or host name.
      • A network designation in CIDR notation, for example, 2001:db8::/48.
      • any: No limit to IPv6 addresses that can access the service-type.

      Repeat this step to list additional IP addresses or networks.

    • To limit access to hosts connected through a specified interface on the Connect EZ 8 device:
      (config)> add service iperf acl interface end value
(config)>

      Where value is an interface defined on your device.

      Use ... network interface ? to display interface information:

      Repeat this step to list additional interfaces.

    • To limit access based on firewall zones:
      (config)> add service iperf acl zone end value
(config)>

      Where value is a firewall zone defined on your device, or the any keyword.

      Type ... firewall zone ? at the config prompt:

      (config)> ... firewall zone ?

Zones: A list of groups of network interfaces that can be referred to by packet
filtering rules and access control lists.

Example performance test using iPerf3

On a remote host with Iperf3 installed, enter the following command:

$ iperf3 -c device_ip

where device_ip is the IP address of the Connect EZ 8 device. For example: 

$ iperf3 -c 192.168.2.1
