AK/SK authentication: Requests are encrypted using AK/SK pairs. AK/SK authentication is recommended as it is more secure than token authentication. Token Authentication A token is valid for 24 hours. When using a token for authentication, cache it to avoid frequent calling.
DH group 14 DH group 15 DH group 16 DH group 19 DH group 20 DH group 21 Figure 1 PFS Anti-replay Anti-replay uses sequence numbers to protect IPsec encrypted packets against replay attacks, which are initiated by repeatedly sending intercepted data packets.
Policy A policy rule defines the data flow that enters the encrypted VPN connection between the local and customer subnets. You need to configure the source and destination CIDR blocks in each policy rule.
