Default Ciphers
During connection establishment a preset list can be transferred to the VPN connection
partners. The list contains combinations of the three algorithms (Encryption,
Authentication, Key Derivation). To establish a VPN connection, the VPN connection
partner must support at least one of these combinations. The combinations depend on
the phase und the key exchange method (IKE).
