We were disappointed by lack of support for VPN Tunnel over Public IP via AWS's VPC VPN, so we head toward 3rd parties where we found VNS3.
Everything setup nicely and smooth. Configuring the VPN is simple and straightforward, with full tcpdump log to help debug the tunnels (which AWS own VPN also lack).

We soon realized that SCTP protocol is not tunnel through the VPN. Only TCP and UDP. This pain point of VNS3 suddenly turn into an advantage where customer support applied a patch for us which enabled SCTP protocol in VNS3, now our firewall is complete. We are happy, our customers are happy, and yeah, our partners are also happy!
