Figure 159 From LAN to VPN Example Chapter 13 Firewall Screens From VPN Packet Direction You can also apply firewall rules to traffic that comes in through the ZyWALL's VPN tunnels. The ZyWALL decrypts the VPN traffic and then applies the firewall rules. From VPN means traffic that came into the ZyWALL through a VPN tunnel and is going to the selected "to" interface. For example, by default the firewall allows traffic from any VPN tunnel to go to any of the ZyWALL's interfaces, the ZyWALL itself and other VPN tunnels. You could edit the From VPN To LAN default firewall rule to silently block traffic from the VPN tunnels from going to the LAN computers.

From LAN to VPN Example
From VPN Packet Direction
You can also apply firewall rules to traffic that comes in through the ZyWALL’s VPN tunnels.
The ZyWALL decrypts the VPN traffic and then applies the firewall rules.
From VPN
means
traffic that came into the ZyWALL through a VPN tunnel and is going to the selected “to”
interface.
For example, by default the firewall allows traffic from any VPN tunnel to go to any of the
ZyWALL’s interfaces, the ZyWALL itself and other VPN tunnels. You could edit the
From
VPN To LAN
default firewall rule to silently block traffic from the VPN tunnels from going
to the LAN computers.
