Anyone with hands-on experience setting up long-haul VPNs over the Internet knows its not a pleasant exercise. It lies at the core of how the Internet was built, its protocols, and how service providers implemented their routing layer. From the early days of the Internet, routers were shaped by technical constraints.

Source port for UDP or TCP, 0 for other protocols. Destination port for UDP or TCP, type and code for ICMP, or 0 for other protocols. Looking at NetFlow, IPFIX (Internet Protocol Flow Information Export), or even sFlow (a standardized protocol similar to NetFlow) records today, you will find that most everything runs on port 80 or 443.

For example, the trombone effect (the inefficient backhauling of cloud bound traffic through a specific network endpoint) often meant MPLS connectivity to cloud assets was worse than standard Internet connections. As a result, businesses turned to SD-WAN and Internet-based VPN solutions as an alternative. The solution?

Virtual Private Networks (VPNs) have become one of the cornerstones of secure communications over the internet. VPNs have become an established method to ensure privacy, protect data, and are becoming very popular among internet users. However, there has been a lot of confusion around what VPNs can and cannot do. Why Use a VPN Tunnel?
