Can VXLAN users access the Internet through VXLAN interfaces?

VXLAN (Virtual Extensible LAN) is a network virtualization technology that helps to create overlay networks on top of existing physical network infrastructure. One of the key features of VXLAN is its ability to encapsulate Layer 2 Ethernet frames within Layer 4 UDP packets, allowing the use of standard IP networks to transport these frames. This capability can extend Layer 2 networks across Layer 3 boundaries.

When VXLAN users are configured properly, they can indeed access the Internet through VXLAN interfaces. This happens because VXLAN allows for network segmentation and creates virtual networks that can emulate the behavior of traditional Ethernet networks, while also leveraging IP routing to reach external networks like the Internet.

In scenarios where Internet access is required, a proper configuration will include routing capabilities at the edge of the VXLAN overlay. This means an external router or gateway can route traffic from the VXLAN network to the Internet. By using NAT (Network Address Translation) and firewall rules, users within a VXLAN segment can communicate with external IP addresses over the Internet.

Therefore, the assertion that users can access the Internet through VXLAN interfaces is accurate, provided the necessary routing and network configurations are in place.
