Advanced Configuration
From the Advanced Settings screen you can adjust the settings for specific VPN tunnels.
Phase 1 Phase 1 is used to create a security association (SA), often called the IKE SA. After Phase 1 is completed, Phase 2 is used to create one or more IPSec SAs, which are then used to key IPSec sessions.
Operation Mode There are two modes: Main and Aggressive, and they exchange the same IKE payloads in different sequences. Main mode is more common; however, some people prefer Aggressive mode because it is faster. Main mode is for normal usage and includes more authentication requirements than Aggressive mode. Main mode is recommended because it is more secure. No matter which mode is selected, the VPN Router will accept both Main and Aggressive requests from the remote VPN device. If a user on one side of the tunnel is using a Unique Firewall Identifier, this should be entered under the User Name field.
