The branch-to-hub to hub-to-branch topology in Azure Virtual WAN enables efficient branch-to-branch communication by routing traffic through connected hubs. This improves data transfer speed and reliability between branches without needing direct connections between all sites, simplifying management while maintaining performance.

The branch-to-branch topology in Azure Virtual WAN is characterized by direct connectivity between branches through the Virtual WAN backbone, which reduces dependency on centralized hubs. This results in a simplified network architecture, lowering latency and optimizing routing between branch locations.

Azure Route Server enables dynamic route exchange using BGP between your Azure virtual network and network virtual appliances (NVAs) or on-premises networks. It provides a centralized and scalable solution for route management, allowing seamless integration of routing updates without manual configuration changes.

In a FortiGate active-active HA deployment in Azure, synchronization between instances is achieved using:

FortiGate Clustering Protocol (FGCP) – This is the primary protocol used to synchronize configuration and session information between HA peers.

Heartbeat interfaces – These interfaces are specifically configured to exchange HA state and sync data between the FortiGate VMs, ensuring cluster consistency.

The FortiGate VM and the Windows Server VM are in different subnets but within the same Production virtual network, which means they can communicate by default unless restricted. Azure allows ICMP between subnets, but Windows VMs have ICMP blocked by default in their firewall settings. Therefore, the likely reason for the ping failure is that the Windows Server’s firewall is blocking ICMP (ping) traffic.

The first and most direct diagnostic step is to verify the BGP peering status on both the FortiGate VM and Azure Route Server. If BGP peering is not established or is in an idle or down state, route propagation will fail. This check confirms whether the two systems are communicating and exchanging routes as expected.

The Reverse Proxy mode is the most appropriate FortiWeb operation mode for this scenario. In this mode, FortiWeb sits between internet users and the Linux web servers, terminating client connections and then forwarding requests to the backend servers. This enables deep inspection, protection from web attacks (like SQL injection and XSS), and full WAF functionality, making it ideal for securing front-end web servers exposed to the internet.

The route server subnet in Azure is a dedicated subnet that hosts the Azure Route Server, which functions as the hub for dynamic routing information exchange between Azure virtual networks and BGP-enabled network virtual appliances (NVAs) or on-premises routers. It enables seamless and centralized route propagation.

Azure Route Server simplifies dynamic routing by allowing your FortiGate VMs to exchange BGP routes directly with Azure’s networking fabric. This eliminates the need to manually update route tables and enables seamless, centralized communication between on-premises branches and Azure resources through both VPN Gateway and ExpressRoute Gateway.

Azure ExpressRoute provides dedicated private connections between on-premises infrastructure and Azure data centers, bypassing the public internet. This results in more predictable latency, higher reliability, and better security, making it ideal for mission-critical workloads.
