Advanced Container Apps Networking: VNet Integration and Centralized Firewall Traffic Logging

Azure community,

I recently documented a networking scenario relevant to Azure Container Apps environments where you need to control and inspect application traffic using a third-party network virtual appliance.

The article walks through a practical deployment pattern:

• Integrate your Azure Container Apps environment with a Virtual Network.

• Configure user-defined routes (UDRs) so that traffic from your container workloads is directed toward a firewall appliance before reaching external networks or backend services.

• Verify actual traffic paths using firewall logs to confirm that routing policies are effective.

This pattern is helpful for organizations that must enforce advanced filtering, logging, or compliance checks on container egress/ingress traffic, going beyond what native Azure networking controls provide. It also complements Azure Firewall and NSG controls by introducing a dedicated next-generation firewall within your VNet.

If you’re working with network control, security perimeters, or hybrid network architectures involving containerized workloads on Azure, you might find it useful.
