VPN Gateway limitations
Site-to-site only
Only site-to-site connections are supported. The VPN service does not support end users connecting their endpoints directly to the VPN service.
IPv4 only
Both SDN Private Networks and the VPN service only support IPv4 subnets. Using IPv6 is currently not possible.
Internet Key Exchange versions
Only IKEv2 (Internet Key Exchange) is supported. For enhanced security, IKEv1 is not supported.
