Tutorial 3: Create Secure Connections Across
the Internet
These sections cover using VPN to create secure connections across the Internet.

3.1 IPSec VPN

Besides using the VPN quick setup wizard to configure settings for an IPSec VPN tunnel, you can use
the Configuration > VPN > IPSec VPN screens to configure and activate or deactivate VPN
gateway and IPSec VPN connection policies. You can also connect or disconnect IPSec VPN
connections.
• Use the VPN Gateway screens to manage the USG's VPN gateways. A VPN gateway specifies the
IPSec routers at either end of a VPN tunnel and the IKE SA settings (phase 1 settings). You can also
activate or deactivate each VPN gateway.
• Use the VPN Connection screens to specify which IPSec VPN gateway an IPSec VPN connection
policy uses, which devices behind the IPSec routers can use the VPN tunnel, and the IPSec SA
settings (phase 2 settings). You can also activate or deactivate and connect or disconnect each VPN
connection (each IPSec SA).
