Hello Changdev Hattikar

When facing speed issues while using a client VPN through vMX on Azure, there could be several factors contributing to the problem. Here are some potential solutions and troubleshooting steps to improve the speed:

Network Bandwidth:

Check the network bandwidth settings on your vMX instance. Ensure that it is configured appropriately to handle the expected traffic volume.

Review the allocated resources (CPU, memory, and network) for the vMX instance and consider increasing them if necessary.

VPN Gateway Configuration:

Check the configuration settings of your Azure VPN Gateway and vMX instance. Ensure that they are properly configured and match the desired performance requirements.

Verify that the VPN Gateway SKU (Standard or High-Performance) is appropriate for your needs. High-Performance SKU offers better throughput capabilities.

Consider using a dedicated VPN Gateway instead of a shared one if you require higher performance.

Network Latency:

Assess the network latency between your client device and the vMX instance. Latency can affect the overall speed and performance.

Use network diagnostic tools such as ping or traceroute to measure and analyze the latency between the client and the vMX instance.

Consider optimizing your network routes to minimize latency.

Network Security:

Review your network security settings, such as firewall rules and VPN encryption protocols. Ensure that they are not excessively restrictive, causing performance degradation.

Verify that your VPN encryption settings are appropriate for the level of security needed. Using a higher encryption level can impact performance.

Network Monitoring:

Implement network monitoring tools or services to track and analyze the network traffic flow, identifying any bottlenecks or areas of congestion.

Monitor the resource utilization of the vMX instance, VPN Gateway, and other relevant components to identify potential performance issues.

Network Optimization:

Optimize your network configuration by applying best practices and recommended settings for VPN connections and vMX deployment in Azure.

Consult Azure documentation and resources for guidance on optimizing VPN performance in Azure.

Remember to monitor and document the observed speed issues, network configurations, and any changes you make during the troubleshooting process. This information will be valuable when seeking support or further investigating the problem.

Hello, Subrothodas-9589,

Thanks for your response. I do not see this option to check Do you have anything to verify this?

Check the network bandwidth settings on your vMX instance. Ensure that it is configured appropriately to handle the expected traffic volume
