Configure the web administration service

The web administration service allows you to monitor and configure the IX30 device by using the WebUI, a browser-based interface.

By default, the web administration service is enabled and uses the standard HTTPS port, 443. The default access control for the service uses the Internal firewall zone, which means that only devices connected to the IX30's LAN can access the WebUI. If this configuration is sufficient for your needs, no further configuration is required. See Allow remote access for web administration and SSH for information about configuring the web administration service to allow access from remote devices.

Required configuration items

    • 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 web administration 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 web administration 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 web administration 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 web administration service.
      4. Click again to list additional IP addresses or networks.
    • To limit access to hosts connected through a specified interface on the device:

        See Firewall configuration for information about firewall zones.

      4. Click again to allow access through additional firewall zones.
  6. Multicast DNS (mDNS) is enabled by default. mDNS is a protocol that resolves host names in small networks that do not have a DNS server. To disable mDNS, or enable it if it has been disabled, click Enable mDNS.
  7. For SSL certificate, if you have your own signed SSL certificate, paste the certificate and private key. If SSL certificate is blank, the device will use an automatically-generated, self-signed certificate.
    • The SSL certificate and private key must be in PEM format.
    • The private key can use one of the following algorithms:
      • RSA
      • DSA
      • ECDSA
      • ECDH

        • Note Password-protected certificate keys are not supported.

    1. Generate the SSL certificate and private key, for example:

      # openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem

    2. Paste the contents of certificate.pem and key.pem into the SSL certificate field. The contents of the certificate.pem must be first. For example:

  8. View is set to Auto by default and normally should not be changed.
