may vary depending on which model you’re configuring. Please see the device’s
User’s Guide for more information about any of these screens or fields.

From, To
Select the directions of travel of packets that you want to check. Select
or clear a row or column’s first check box (with the interface label) to
select or clear the interface’s whole row or column.
For example,
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 or the device itself. The device does not
check packets traveling from a LAN computer to another LAN computer
on the same subnet.
From VPN
means traffic that came into the device through a VPN
tunnel and is going to the selected “to” interface. For example,
From
VPN To LAN
specifies the VPN traffic that is going to the LAN or
terminating at the device’s LAN interface. The device checks the traffic
after decrypting it.
To VPN
is traffic that comes in through the selected “from” interface
and goes out through any VPN tunnel. For example,
From LAN To VPN
specifies the traffic that is coming from the LAN and going out through a
VPN tunnel. The device checks the traffic before encrypting it.
From VPN To VPN
means traffic that comes in through a VPN tunnel
and goes out through (another) VPN tunnel or terminates at the device.
This is the case when the device is the hub in a hub-and-spoke VPN.
This is also the case if you allow someone to use a service (like Telnet or
HTTP) through a VPN tunnel to manage the device. The device checks
the traffic after decrypting it (before encrypting it again).
Note: The VPN connection directions apply to the traffic going to or
from the device’s VPN tunnels. They do not apply to other
VPN traffic for which the device is not one of the gateways
(VPN pass-through traffic).
