Doing Some Initial Configuration
Before you start messing around with the settings or experimenting with the services, you should at least change to an encrypted HTTPS connectionand change the default password of FreeNAS.
On the main web GUI menu, click System > General. Scroll down to the WebGUI section, choose HTTPS for the Protocol option, scroll down to the bottom of the page, and click Save.
For the changes to take effect, you must reboot FreeNAS. Before doing so, you may want to scroll down to the Time section to set the date and time information.
Now click the reboot link in the status area near the top of the page.
Now once it boots back up, click System > General again, and then click the Password tab.
Type in "freenas" for the Old Password, type in a new password in the two boxes, and click Save.
Again, you must reboot for the changes to take effect; click the reboot link.
