Troubleshooting AWS Client VPN: Verify the bandwidth limit for a Client VPN endpoint

Problem

I need to verify the bandwidth limit for a Client VPN endpoint.

Cause

The throughput depends on multiple factors, such as the capacity of your connection from your location, and the network latency between your Client VPN desktop application on your computer and the VPC endpoint. There is also a 10 Mbps bandwidth limit per user connection.

Solution

Run the following commands to verify the bandwidth.

sudo iperf3 -s -V

On the client:

sudo iperf -c server IP address -p port -w 512k -P 60
