Bases: _SerdeShape

The Amazon Web Services Site-to-Site VPN tunnel options to modify.

Attributes

dpd_timeout_action class-attribute instance-attribute

phase1_lifetime_seconds class-attribute instance-attribute
phase1_lifetime_seconds: int | None = ...

The lifetime for phase 1 of the IKE negotiation, in seconds.

Constraints: A value between 900 and 28,800.

Default: 28800

phase2_dh_group_numbers class-attribute instance-attribute
phase2_dh_group_numbers: list[Phase2DHGroupNumbersRequestListValue] | None = ...

One or more Diffie-Hellman group numbers that are permitted for the VPN tunnel for phase 2 IKE negotiations.

Valid values: 2 | 5 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24

phase2_encryption_algorithms class-attribute instance-attribute

Valid values: SHA1 | SHA2-256 | SHA2-384 | SHA2-512

phase2_lifetime_seconds class-attribute instance-attribute
phase2_lifetime_seconds: int | None = ...

The lifetime for phase 2 of the IKE negotiation, in seconds.

Constraints: A value between 900 and 3,600. The value must be less than the value for Phase1LifetimeSeconds.

Default: 3600

pre_shared_key class-attribute instance-attribute
pre_shared_key: str | None = ...
