Firewall
Select Enabled or Disabled to enable or disable the firewall.
If the firewall is enabled, the system refuses all requests from the internet. Only
packets from the LAN which are belonging to defined connections and for which the
status database is created can pass the firewall and can have access to the LAN.
By default the firewall is enabled. To expose all hosts in the LAN to the internet you
can disable the firewall.
