Chapter 23 IPSec VPN Application Scenarios The ZyWALL's application scenarios make it easier to configure your VPN connection settings. Table 113 IPSec VPN Application Scenarios SITE-TO-SITE SITE-TO-SITE WITH REMOTE ACCESS DYNAMIC PEER (SERVER ROLE) REMOTE ACCESS (CLIENT ROLE) Choose this if the remote IPSec router has a static IP address or a domain name. This ZyWALL can initiate the VPN tunnel. The remote IPSec router can also initiate the VPN tunnel if this ZyWALL has a static IP address or a domain name. Choose this if the remote IPSec router has a dynamic IP address. You don't specify the remote IPSec router's address, but you specify the remote policy (the addresses of the devices behind the remote IPSec router). This ZyWALL must have a static IP address or a domain name. Only the remote IPSec router can initiate the VPN tunnel. Choose this to allow incoming connections from IPSec VPN clients. The clients have dynamic IP addresses and are also known as dial-in users. You don't specify the addresses of the client IPSec routers or the remote policy. This creates a dynamic IPSec VPN rule that can let multiple clients connect. Only the clients can initiate the VPN tunnel. Choose this to connect to an IPSec server. This ZyWALL is the client (dial-in user). Client role ZyWALLs initiate IPSec VPN connections to a server role ZyWALL. This ZyWALL can have a dynamic IP address. The IPSec server doesn't configure this ZyWALL's IP address or the addresses of the devices behind it. Only this ZyWALL can initiate the VPN tunnel.
