On the receiver, create an Allow rule on the Windows Firewall to allow the Latte.exe traffic to arrive. Test VMs running Windows Load Latte.exe onto the VMsĬonsider putting Latte.exe in separate folder, such as c:\tools Allow Latte.exe through the Windows firewall NTTTCP is an alternative solution for testing. Then run iPerf in server mode, and set it to listen on port 5001 as the following commands: cd c:\iperf-3.1.2-win65 On the server node, change to the directory where iperf3.exe is extracted. Common Linux OS-layer firewalls include iptables, ufw, or firewalld. Custom images that are secured may need ports opened explicitly. If there is an application listening on a port, the traffic is allowed through. To remove the rule when testing is complete, run this command: netsh advfirewall firewall delete rule name="Open Port 5001" protocol=TCP localport=5001Īzure Linux: Azure Linux images have permissive firewalls. Windows: Run the following command as an administrator: netsh advfirewall firewall add rule name="Open Port 5001" dir=in action=allow protocol=TCP localport=5001 On both nodes, enable a firewall exception for port 5001. Run iPerf (iperf3.exe)Įnable an NSG/ACL rule allowing the traffic (for public IP address testing on Azure VM).

Once this test is completed, we recommend that you reverse the roles of the nodes to test both upload and download throughput on both nodes. When testing between two nodes, one node acts as the server, and the other node acts as a client. It generates statistics based on experimentation that measures the bandwidth available between client and server nodes. It solely produces self-generated TCP traffic from one end to the other. This tool does not perform any read/write operations to disk. The tool we use for this test is iPerf, which works on both Windows and Linux and has both client and server modes. This validation should be performed during non-peak hours, as VPN tunnel throughput saturation during testing does not give accurate results. Validate network throughput by using performance tools VPN Gateway throughput is an aggregate of all Site-to-Site\VNET-to-VNET, or Point-to-Site connections. If you are not experiencing the expected Internet bandwidth, you may also contact your ISP. To resize a virtual machine, see Resize a VM. To resize an Azure VPN Gateway, see Changing a gateway SKU. If your calculated throughput does not meet your application's baseline throughput requirements, you must increase the bandwidth of the resource that you identified as the bottleneck.
For help, see the "Gateway SKUs" section of About VPN Gateway. Determine your Azure VPN gateway throughput limits.Determine your application's baseline throughput requirements.The following diagram shows the logical connectivity of an on-premises network to an Azure virtual network through VPN.Ĭalculate the maximum expected ingress/egress On-premises VPN device (View a list of validated VPN devices.).The VPN gateway connection involves the following components: If you're unable to solve the issue by using the following information, contact support.
