# How to block internet access using AB Tutor Policies in AB Tutor

**This article applies to:**
* AB Tutor v8
One of the policies within AB Tutor is ‘Block Internet Access’. This works by blocking all access to specified Internet ports.
Create a ‘Block Internet Access’ Policy
Click right on **All Policies – New Policy**
Highlight 'Block internet Access' and press 'next'.
Enter a name to identify this policy.
You can then choose to create a button on the toolbar, if you wish.

Applying the Policy on the Remote Machine
Select **For a Specified Time** which will remove the policy after a set amount of time.
Select **Permanent** if you want this policy to apply to all users who use the machine even when the Tutor program is not running or the remote machine is rebooted.
**Warning: **We recommend that you do not set any permanent policies close to the end of your trial of AB Tutor. Once the 30 days’ trial has run out, the policies (especially the Windows control policies) that you have applied will remain in force and cannot easily be removed. Therefore please make sure that you remove all permanent policies well before the trial expires.
Administrator Security
You will only see this if you are logged on as an Administrator.
**Protected **– If this option is set, then tutors will not be able to apply, edit or remove this policy.
**If removed re-apply after X mins** – You may want to apply a policy that remains active except during a lesson.  This will allow the tutor to remove the policy during the lesson and the policy will be automatically re-applied after the set time, with or without the tutors intervention.
Press **Next**
 
Policy Time
If you select a Permanent policy, then you are given the option to control when that policy will be active throughout the day.
By default, the policy is active all day every day. Use click and drag to set the policy to be active/inactive in half hour chunks. If you want to set the time slots more accurately, you can drag the ends of the time blocks or right click on a block and select **edit** to enter the times manually.
Click **Next**
Select the communication ports on the remote machines that will prevent any application from accessing the internet through that port.

Click **‘Finish’**
You can now apply this policy to the remote clients.
