Network → Global Configuration, shown in Figure 5.1a, allows you to set non-interface specific network settings.

Figure 5.1a: Global Configuration Screen

Table 5.1a summarizes the settings that can be configured using the Global Configuration tab. The hostname and domain will be pre-filled for you, as seen in Figure 5.1a, but can be changed to meet the local network's requirements.

If you will be using Active Directory, set the IP address of the DNS server used in the realm.

If your network does not have a DNS server or NFS, SSH, or FTP users are receiving "reverse DNS" or timeout errors, add an entry for the IP address of the FreeNAS® system in the "Host name database" field.

NOTE: if you add a gateway to the Internet, make sure that the FreeNAS® system is protected by a properly configured firewall.

Table 5.1a: Global Configuration Settings

Setting Value Description
Hostname string system host name
Domain string system domain name
IPv4 Default Gateway IP address typically not set (see NOTE below)
IPv6 Default Gateway IP address typically not set (see NOTE below)
Nameserver 1 IP adress primary DNS server
Nameserver 2 IP address secondary DNS server
Nameserver 3 IP address tertiary DNS server
Enable netwait feature checkbox if enabled, network services will not be started at boot time until the interface is able to ping the addresses listed in Netwait IP list
Netwait IP list string if Enable netwait feature is checked, list of IP addresses to ping; otherwise, ping the default gateway
Host name database string used to add one entry per line which will be appended to /etc/hosts; use the format IP_address space hostname where multiple hostnames can be used if separated by a space

NOTE: In many cases, a FreeNAS® configuration will deliberately exclude default gateway information as a way to make it more difficult for a remote attacker to communicate with the server. While this is a reasonable precaution, such a configuration does not restrict inbound traffic from sources within the local network. However, omitting a default gateway will prevent the FreeNAS® system from communicating with DNS servers, time servers, and mail servers that are located outside of the local network. In this case, it is recommended that Static Routes be added in order to reach external DNS, NTP, and mail servers which are configured with static IP addresses.
