ZyWALL P1 User's Guide
DESCRIPTION
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
ZyWALL or the ZyWALL itself. The ZyWALL 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 ZyWALL through the 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 ZyWALL's LAN
interface. The ZyWALL checks the traffic after decrypting it.
To VPN is traffic that comes in through the selected "from" interface and goes out
through the VPN tunnel. For example, From LAN To VPN specifies the traffic that
is coming from the LAN and going out through the VPN tunnel. The ZyWALL
checks the traffic before encrypting it.
From VPN To VPN means traffic that comes in through the VPN tunnel and
terminates at the ZyWALL. This is the case if you allow someone to use a service
(like Telnet or HTTP) through the VPN tunnel to manage the ZyWALL. The
ZyWALL checks the traffic after decrypting it (before encrypting it again).
Note: The VPN connection directions apply to the traffic going to or
from the ZyWALL's VPN tunnel. They do not apply to other
VPN traffic for which the ZyWALL is not one of the gateways
(VPN pass-through traffic).
Select the interface(s) where you want the ZyWALL to scan files for viruses.
