Hostname Option Support for DHCP Clients

Send the hostname of a DHCP client interface to the DHCP server, which can register the hostname with the DNS server. The DNS server can automatically manage hostname-to-dynamic IP address resolutions.
When a firewall interface is a DHCP client that is assigned a dynamic IPv4 address by a DHCP server, the changing IP address makes it difficult for external hosts to identify the interface. You can now assign a hostname to a DHCP client interface on the firewall and send that hostname (Option 12) to a DHCP server, which can register the hostname with the DNS server. The DNS server can automatically manage hostname-to-dynamic IP address resolutions.
  1. Select
    Send Hostname
    and accept the firewall hostname (the default) or enter a unique hostname for the interface.
