Enable service discovery (mDNS)

Multicast DNS (mDNS) is a protocol that resolves host names in small networks that do not have a DNS server. You can enable the IX15 device to use mDNS.

To enable mDNS:

  1. Choose the management interface you want to use to access your device. Click a dropdown for instructions.

    1. Log in to Digi Remote Manager.

    1. Navigate to the device's dashboard.

    1. Log in to your device's Web UI.

    Log in to your device's Admin CLI via an SSH client, Telnet client, or terminal emulator.

  2. Configure the settings.

    1. Click to open the device's configuration menu.

      • In Digi Remote Manager, on the device dashboard, click Settings.

      • In the Web UI, click Device Configuration.

    2. Click Services > Service Discovery (mDNS).
    3. Enable the mDNS service.
      • 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 mDNS service. 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 mDNS service.
        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 mDNS service. 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 mDNS service.
        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. At the CLI prompt, type config and then press Enter.

    2. Enable the mDNS service:

      (config)> service mdns enable true
(config)>
      • To limit access to specified IPv4 addresses and networks:
        (config)> add service mdns 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 mDNS service.

        Repeat this step to list additional IP addresses or networks.

      • To limit access to specified IPv6 addresses and networks:
        (config)> add service mdns 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 mDNS service.

        Repeat this step to list additional IP addresses or networks.

      • To limit access to hosts connected through a specified interface on the IX15 device:
        (config)> add service mdns acl interface end value
(config)>

        Where value is an interface defined on your device.

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

        (config)> ... network interface ?

      • To limit access based on firewall zones:
        (config)> add service mdns 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.
