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
|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.
