The Firewall policy specifies how the firewall protects computers.
By default, the Sophos Client Firewall is enabled and blocks all non-essential
traffic. Before you use it throughout your network, you should configure it to allow
the applications you want to use. See Set up a basic firewall policy.
For a full list of the default firewall settings, see knowledgebase article
