 ** EnableAcceleration **   
Indicate whether to enable acceleration for the VPN connection.  
Default: `false`   
Type: Boolean  
Required: No

 ** LocalIpv4NetworkCidr **   
The IPv4 CIDR on the customer gateway (on-premises) side of the VPN connection.  
Default: `0.0.0.0/0`   
Type: String  
Required: No

 ** LocalIpv6NetworkCidr **   
The IPv6 CIDR on the customer gateway (on-premises) side of the VPN connection.  
Default: `::/0`   
Type: String  
Required: No

 ** OutsideIpAddressType **   
The type of IP address assigned to the outside interface of the customer gateway device.  
Valid values: `PrivateIpv4` \$1 `PublicIpv4` \$1 `Ipv6`   
Default: `PublicIpv4`   
Type: String  
Required: No

 ** RemoteIpv4NetworkCidr **   
The IPv4 CIDR on the AWS side of the VPN connection.  
Default: `0.0.0.0/0`   
Type: String  
Required: No

 ** RemoteIpv6NetworkCidr **   
The IPv6 CIDR on the AWS side of the VPN connection.  
Default: `::/0`   
Type: String  
Required: No

 ** StaticRoutesOnly **   
Indicate whether the VPN connection uses static routes only. If you are creating a VPN connection for a device that does not support BGP, you must specify `true`. Use [CreateVpnConnectionRoute](API_CreateVpnConnectionRoute.md) to create a static route.  
Default: `false`   
Type: Boolean  
Required: No

 ** TransportTransitGatewayAttachmentId **   
The transit gateway attachment ID to use for the VPN tunnel.  
Required if `OutsideIpAddressType` is set to `PrivateIpv4`.  
Type: String  
Required: No

 ** TunnelBandwidth **   
 The desired bandwidth specification for the VPN tunnel, used when creating or modifying VPN connection options to set the tunnel's throughput capacity. `standard` supports up to 1.25 Gbps per tunnel, while `large` supports up to 5 Gbps per tunnel. The default value is `standard`. Existing VPN connections without a bandwidth setting will automatically default to `standard`.   
Type: String  
Valid Values: `standard | large`   
Required: No

 ** TunnelInsideIpVersion **   
Indicate whether the VPN tunnels process IPv4 or IPv6 traffic.  
Default: `ipv4`   
Type: String  
Valid Values: `ipv4 | ipv6`   
Required: No
