ZONE FIREWALL
ZONE DEFINITION
A Zone is a group of network interfaces. By default all interfaces within
a zone are allowed to initialize network communication with each
other, however any network traffic initialized outside of a zone to the
interfaces within the zone will be denied.
To add a zone, click
Add .
FILTER POLICIES
A Filter Policy is a one-way filter applied to initialized network traffic flowing from one zone to another. A
Filter Policy needs to be assigned to a Forwarding for it to take effect. Filter Policies can either be Added,
Edited, or Removed.
•
Default Allow All is a preconfigured policy to
allow all traffic initialized from one zone to flow
to another zone. The state of the connection is
tracked to allow responses to traverse the zones
back to the source. LAN to WAN forwardings use
this policy by default. The policy can be removed or
altered to filter the traffic flow.
• Default Deny All is a preconfigured policy to deny
all traffic initialized from one zone to be blocked
to another zone. WAN to LAN forwardings use this
policy by default. The policy can be removed or
altered to filter the traffic flow.
