Azure Firewall Auto-Learn SNAT Routes Is Generally Available
The SNAT problem that needed solving Here is a scenario that plays out in half the hybrid networks I have seen: traffic from Azure toward an on-premises range that is not one of the standard private ranges silently gets source-NATted by Azure Firewall. The on-prem firewall sees an unexpected source IP, a policy match fails, […]
Azure Multicloud Interconnect: Microsoft and AWS finally wired the clouds together
Microsoft and AWS announced a joint service this week that neither company would have shipped five years ago: a managed private connection between the two clouds, provisioned from both portals, operated by both providers. Azure Multicloud Interconnect is in public preview now, with AWS as the first supported partner, and it replaces what has historically […]
Azure SRE Agent VNet Integration Reaches General Availability with Private Network Controls
Microsoft has officially announced the general availability of Virtual Network (VNet) integration for Azure SRE Agent. The capability allows operations and platform teams to deploy and operate Microsoft’s autonomous site reliability engineering agent entirely within their private virtual network topology. By routing the agent’s outbound management traffic through dedicated subnets, organizations can enforce corporate Network […]
Unpatched Flaw in Calix Fiber Gateways Lets Attackers Bypass NAT to Expose Internal Devices
Residential gateways and broadband routers form the first and often only line of defense protecting home and small office networks from direct Internet exposure. Security researchers have disclosed an unpatched vulnerability in widely deployed Calix GS7 XGS (GS5239XG) residential gateways that allows unauthenticated remote attackers on the public Internet to bypass Network Address Translation (NAT) […]
eBPF Host Routing Hits General Availability in Advanced Container Networking Services for AKS
Running high throughput or low latency distributed systems on Kubernetes often hits an unexpected bottleneck inside the Linux kernel network stack. Microsoft has officially announced the general availability of eBPF Host Routing within Advanced Container Networking Services (ACNS) for Azure Kubernetes Service (AKS). This release fundamentally transforms how network packets move between pods and nodes […]
Explicit Proxy in Azure Firewall Goes GA: An Alternative to Route-Based Inspection
Azure Firewall’s explicit proxy mode reached general availability this month. For anyone who has fought with user-defined routes to steer outbound traffic through a firewall, this is a meaningful change. Instead of relying on transparent, route-based interception, you can now point applications and browsers directly at the firewall as a proxy. Explicit proxy versus the […]
Azure Private Link now works over IPv6
Azure Private Link has started supporting IPv6, in public preview. The update lets you reach Azure PaaS services like Azure Storage and Azure SQL Database over IPv6-based connectivity, using IPv6 private endpoints from clients inside an Azure virtual network. For anyone running an IPv6 or dual-stack estate, this closes a long standing gap in the […]
Azure Virtual Network routing appliance hits general availability
Azure has made its Virtual Network routing appliance generally available for production workloads. The move gives teams a managed alternative to the usual stack of VM-based network virtual appliances (NVAs) that have anchored hub-and-spoke designs for years. It also marks August 4, 2026 as the date the service stopped being a preview experiment and became […]
Azure Firewall Now Supports HTTP Header Insertion at GA
Azure Firewall now supports HTTP header insertion in application rules, and this is one of those features that sounds small but opens up a lot of useful scenarios for network security teams. The feature went GA on July 27, 2026, and it lets you add or overwrite HTTP request headers directly from the firewall without […]
Route-Maps for Azure Route Server Now in Public Preview
Microsoft has launched the public preview of Route-Maps for Azure Route Server, giving network engineers fine-grained control over BGP routing in hybrid cloud environments. Route maps let you manipulate how routes are advertised and received across VPN and ExpressRoute connections, moving beyond the static route tables that made complex topologies painful to manage. What route […]
