Zone Control
From/To The firewall rules are grouped by the direction of packet travel and their zones ( WAN , LAN ,
WLAN , DMZ , EXTRA and ROUTER ). By default, the firewall allows passage of packets traveling in
the same zone (a LAN to a LAN, a WAN to a WAN). Here are some example descriptions of the
directions of travel.
From LAN To LAN means packets traveling from a computer on one LAN subnet to a computer
on another LAN subnet on the LAN interface of the device.
You can define the EXTRA zone to include the VPN connection. The Router zone can only be
controlled in ingress direction “to” because it is reserved for the router’s CPU. However, packets
sent from the router zone are always permitted. For example, if your packet come from a LAN
zone and is going to the Router zone. The SBG will apply the firewall rules to the LAN packets if
you did not click the
Permit check box.
When Permit box is unchecked and Log box is checked, it means the “dropped” packets will be
logged. When both Permit and Log boxes are checked, it means the “permitted” packets will
be logged.
Permit Click the check box Permit to allow the passage of the packets.
Log Click the check box Log to create a log when an action from Firewall rule is taken.
