7 Firewall
You can use the ZyWALL without configuring the firewall.
The ZyWALL’s firewall is pre-configured to protect your LAN from attacks from the Internet. By default, no
traffic can enter your LAN unless a request was generated on the LAN first. The ZyWALL allows access to the
DMZ from the WAN or LAN, but blocks traffic from the DMZ to the LAN.
8 VPN Rule Setup
A VPN (Virtual Private
Network) tunnel gives you a

IPSec routers at either end of a
VPN tunnel.
A network policy specifies
which devices (behind the
IPSec routers) can use the
VPN tunnel.
