![]() To connect to multiple VPCs and and achieve higher throughput limits, use AWS Transit Gateway. For AWS Direct Connect connection on a Virtual Private Gateway, the throughput is bound by the Direct Connect physical port itself. Multiple VPN connections to the same Virtual Private Gateway are bound by an aggregate throughput limit from AWS to on-premises of up to 1.25 Gbps. Q: Is there an aggregated throughput limit for Virtual Private Gateway?Ī: Virtual Private Gateway has an aggregate throughput limit per connection type. If your VPN connection is to a Virtual Private Gateway, aggregated throughput limits would apply. Q: What is the approximate maximum throughput of a Site-to-Site VPN connection?Ī: Each AWS Site-to-Site VPN connection has two tunnels and each tunnel supports a maximum throughput of up to 1.25 Gbps. ![]() Q: If my device is not listed, where can I go for more information about using it with Amazon VPC?Ī: We recommend checking the Amazon VPC forum as other customers may be already using your device. Q: What customer gateway devices are known to work with Amazon VPC?Ī: In The network administrator guide, you will find a list of the devices meeting the aforementioned requirements, that are known to work with hardware VPN connections, and that will support in the command line tools for automatic generation of configuration files appropriate for your device. If you would like a specific proposal for rekey, we recommend that you use Modify VPN Tunnel Options to restrict the tunnel options to the specific VPN parameters you require. Q: What algorithms does AWS propose when an IKE rekey is needed?Ī: By default, then VPN endpoint on AWS side will propose AES-128, SHA-1 and DH group 2. Q: Which Diffie-Hellman groups do you support?Ī We support the following Diffie-Hellman (DH) groups in Phase 1 and Phase 2. In addition to the above capabilities, devices supporting dynamically-routed Site-to-Site VPN connections must be able to:Įstablish Border Gateway Protocol (BGP) peeringīind tunnels to logical interfaces (route-based VPN) Perform packet fragmentation prior to encryption Utilize Diffie-Hellman (DH) Perfect Forward Secrecy in "Group 2" mode, or one of the additional DH groups we support Customer gateway devices supporting statically-routed VPN connections must be able to:Įstablish IKE Security Association using Pre-Shared KeysĮstablish IPsec Security Associations in Tunnel mode Q: Which customer gateway devices can I use to connect to Amazon VPC?Ī: You can create two types of AWS Site-to-Site VPN connections: statically routed VPN connections and dynamically-routed VPN connections. An Internet gateway is not required to establish a Site-to-Site VPN connection.Ī: IPsec is a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a data stream. Data transferred between your VPC and datacenter routes over an encrypted VPN connection to help maintain the confidentiality and integrity of data in transit. Amazon supports Internet Protocol security (IPsec) VPN connections. Q: How does an AWS Site-to-Site VPN connection work with Amazon VPC?Ī: An AWS Site-to-Site VPN connection connects your VPC to your datacenter. From there, it can access the Internet via your existing egress points and network security/monitoring devices. The NAT gateway or NAT instance allows outbound communication but doesn’t allow machines on the internet to initiate a connection to the privately addressed instances.įor VPCs with a hardware VPN connection or Direct Connect connection, instances can route their Internet traffic down the virtual private gateway to your existing datacenter. These instances use the public IP address of the NAT gateway or NAT instance to traverse the internet. Instances without public IP addresses can route their traffic through a network address translation (NAT) gateway or a NAT instance to access the internet. Q: How do instances without public IP addresses access the Internet?Ī: Instances without public IP addresses can access the Internet in one of two ways: Q: What are the VPN connectivity options for my VPC?Ī: You may connect your VPC to your corporate data center using a Hardware VPN connection via the virtual private gateway.
