Set up a basic firewall policy
By default, the firewall is enabled and blocks all non-essential traffic. Therefore, you should configure it to allow the applications you want to use, and test it before installing it on all computers. See the Sophos Enterprise Console policy setup guide for detailed advice.
For information about preventing network bridging, see Device control policy.
Note When you apply a new or updated policy to computers, applications that were
allowed before may be blocked briefly until the new policy is fully applied. You
should notify your users about this before you apply new policies.
Note If you use role-based administration:
- You must have the Policy setting - firewall right to configure a firewall policy.
- You cannot edit a policy if it is applied outside your active sub-estate.
To set up a basic firewall policy:
After you have set up the firewall, you can view firewall events (for example, applications blocked by the firewall) in the Firewall - Event Viewer.
The number of computers with events over a specified threshold within the last seven days is also displayed on the Dashboard.
