Configuring Security Settings - LEGRAND Server Technology PRO3X User Manual

Enabling this feature also enables Link-Local Multicast Name Resolution (LLMNR) and/or MDNS, which
are required for resolving APIPA host names. See APIPA and Link-Local Addressing.
The service advertisement feature supports both IPv4 and IPv6 protocols.
If you have set a preferred host name for IPv4 and/or IPv6, that host name can be used as the zero
configuration .local host name, that is, <preferred_host_name>.local, where <preferred_host_name> is
the preferred host name you have specified for PRO3X. The IPv4 host name is the first priority. If an IPv4
host name is not available, then use the IPv6 host name.
▶

1) Choose Device Settings > Network Services > Service Advertising.
2) To enable the service advertising, select either or both checkboxes.
• • To advertise via MDNS, select the Multicast DNS checkbox.
• • To advertise via LLMNR, select the Link-Local Multicast Name Resolution checkbox.
3) Click Save.

Configuring Security Settings

The PRO3X provides tools to control access. You can enable the internal firewall, create firewall rules,
and set login limitations. In addition, you can create and install the certificate or set up external
authentication servers for access control. This product supports SHA‑2 TLS certificates.
Creating IP Access Control Rules
IP access control rules (firewall rules) determine whether to accept or discard traffic to/from the PRO3X,
based on the IP address of the host sending or receiving the traffic. When creating rules, keep these
principles in mind:
• • Rule order is important.
