default outbound access

About this tag
Default outbound access in Azure refers to the implicit outbound internet connectivity that Azure previously provided to virtual machines in new virtual networks. Microsoft is changing this behavior: starting March 31, 2026, new Azure VNets and subnets will be private by default, meaning no default outbound access is granted. Users must explicitly configure outbound connectivity using Azure NAT Gateway, Load Balancer outbound rules, or a public IP. This change affects networking, security, and enterprise IT planning for Azure deployments. Discussions on WindowsForum cover the transition, implications for existing workloads, and best practices for ensuring outbound connectivity while maintaining security.
