When you first set up your control tower you must configure the force field settings of the tower. Once you have configured the force field settings to your satisfaction you must click on the Apply button in the lower right corner of the window to activate the force field. Not doing so may leave your starbase force field wide open to hostiles, thieves, squatters and worse. Once the settings have been applied the status should change to "This Force Field Is Active".

When active, the force field is a safe haven for anyone within its boundaries. If you are within a starbase force field you can not be targetted and hostile area of effect weapons can not affect you. Note that this includes the tower itself, in effect the tower can not attack someone within its own force field even if the pilot fulfills any of the tower's defensive parameters.

(Note that the field will only protect your ships from damage and keep hostiles from entering. It will not protect against anyone that can enter the field normally that might have long fingers and take a fancy to your ship.)

You access the options for the force field configuration by right clicking on the control tower and selecting the Manage option. In the control tower window you need to open up the Force Field tab. The following options and information is available in the Force Field tab.

Status
This line will tell if the control tower's force field is active or inactive.

Password
You can set a password to the force field by typing into the fields. This can be helpful when use of the starbase should be restricted to only a few members of a corporation or if people from other corporations need to be given access to the starbase. Note that the passwords are case sensitive.

Restriction Masks
Options checked here can allow or restrict access to the force field to whole groups. Currently you can allow or restrict access to the entire corp that owns the control tower or the entire alliance the corporation is a member of.
