11.3.1 To VPN Packet Direction

The ZyWALL can apply firewall rules to traffic before encrypting it to send through a VPN
tunnel. To VPN means traffic that comes in through the selected "from" interface and goes out
through any of the ZyWALL's VPN tunnels. For example, From LAN To VPN specifies the
traffic that is coming from the LAN and going out through any of the ZyWALL's VPN
tunnels.
For example, by default the From LAN To VPN default firewall rule allows traffic from the
LAN computers to go out through any of the ZyWALL's VPN tunnels. You could configure
the From DMZ To VPN default rule to set the ZyWALL to silently block traffic from the
DMZ computers from going out through any of the ZyWALL's VPN tunnels.

In order to do this, you would configure the SECURITY > FIREWALL > Default Rule
screen as follows.
