Chapter 24 IPSec VPN Application Scenarios The ISG50's application scenarios make it easier to configure your VPN connection settings. Table 121 IPSec VPN Application Scenarios SITE-TO-SITE SITE-TO-SITE WITH DYNAMIC PEER REMOTE ACCESS (SERVER ROLE) REMOTE ACCESS (CLIENT ROLE) Choose this if the remote IPSec router has a static IP address or a domain name. For example, a branch office with an ISG50 or a VPN router with a static IP address. This ISG50 can initiate the VPN tunnel. The remote IPSec router can also initiate the VPN tunnel if this ISG50 has a static IP address or a domain name. Choose this if the remote IPSec router has a dynamic IP address. For example, a branch office with an ISG50 or a VPN router with 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 ISG50 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, including smartphone applications. Smartphone applications require a valid subscription to use. See Chapter 11 on page 229. 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. Choose this to connect to an IPSec server. This ISG50 is the client (dial-in user). Client role ISG50s initiate IPSec VPN connections to a server role ISG50. This ISG50 can have a dynamic IP address. The IPSec server doesn't configure this ISG50's IP address or the addresses of the devices behind it. Only this ISG50 can initiate the VPN tunnel. Only the clients can initiate the VPN tunnel. Finding Out More • See Section 6.6.14 on page 102 for related information on these screens. • See Section 24.4 on page 386 for IPSec VPN background information. • See Section 5.4 on page 77 for the IPSec VPN quick setup wizard. • See Section 7.4 on page 113 for an example of configuring IPSec VPN.
