K02. How to count my VPN tunnels on ZyWALL? 
 
On 3.64, multiple Network Policies (IKE Phase 2) can be mapped to same Gateway policy (IKE Phase 1). 
ZyWALL counts the Network policies as VPN tunnels. 
 
In following example, two network policies, Netowrk_1 & Network_2 are mapped to same gateway 
policy, Gateway_1. In this case, this will be counted as two VPN tunnels. 
 
 
K03. What is VPN? 
A VPN gives users a secure link to access corporate network over the Internet or other public or private 
networks without the expense of lease lines. A secure VPN is a combination of tunneling, encryption, 
authentication, access control and auditing technologies/services used to transport traffic over the Internet 
or any insecure network that uses the TCP/IP protocol suite for communication.
