FreeGuard Testing Methodology
آخرین تأیید: 2026-04-15
This page describes how FreeGuard tests VPN performance, security, and reliability across all server regions. Our testing methodology is transparent and reproducible.
Tools We Use
iperf3
Measures raw TCP/UDP throughput between the test client and a controlled iperf3 server placed at each target location.
ping / mtr
Measures round-trip latency and hop-by-hop packet loss using ICMP echo requests over a 60-second window.
آزمایش نشت DNS
این بررسی یک پرسوجوی A برای freeguardvpn.com به هر ارائهدهنده عمومی DNS-over-HTTPS فهرستشده میفرستد و فقط فراداده پاسخ را نمایش میدهد. نمیتواند resolver بازگشتی DNS دستگاه شما یا استفاده یک درخواست از تونل VPN را مشخص کند.
WebRTC leak checker (headless Chromium)
Automates a headless Chromium session to capture local and public ICE candidates and compares them against the expected VPN IP.
آزمایش نشت IPv6
این endpoint دوپشته بهتنهایی ثابت نمیکند IPv6 تونل یا مسدود شده است. بررسی واقعی به یک probe فقط-IPv6 تحت مالکیت در هر شبکه نیاز دارد.
Wireshark / tshark
Captures live traffic during each test run to confirm all packets flow through the encrypted tunnel and none bypass it.
Test Environment
Hardware
Dedicated bare-metal test machines with 8-core CPUs, 32 GB RAM, and 1 Gbps NIC — ensuring the client is never the bottleneck.
Network Conditions
Tests are run across multiple ISPs per source location, covering fiber, cable, and 4G/LTE connections to capture real-world variance.
Geographic Distribution
Tests are executed from 10+ source countries across Asia, Europe, and North America to reflect global user conditions.
Test Protocol
Each server location follows this standardized step-by-step procedure:
Connect to target VPN server
Establish the tunnel using the FreeGuard client. Wait 10 seconds for routing tables to stabilize.
Verify tunnel IP
Confirm the public IP matches the expected VPN server egress address before any measurements begin.
Run speed test (iperf3)
Execute a 30-second bidirectional iperf3 test. Record download, upload, and jitter.
Measure latency (ping/mtr)
Send 100 ICMP packets to the target. Record min, avg, max RTT and packet loss percentage.
آزمایش نشت DNS
برای بررسی نشت DNS، تنظیمات DNS سیستمعامل، مرورگر و VPN را با ثبت بستهها یا گزارشهای resolver در شبکههای واقعی مقایسه کنید.
Run WebRTC leak test
Launch headless Chromium, collect ICE candidates, and assert no real IP is exposed.
آزمایش نشت IPv6
این endpoint دوپشته بهتنهایی ثابت نمیکند IPv6 تونل یا مسدود شده است. بررسی واقعی به یک probe فقط-IPv6 تحت مالکیت در هر شبکه نیاز دارد.
Disconnect and reset
Tear down the tunnel, flush routing tables, and wait 30 seconds before the next run.
Repeat 3× and average
Perform the full sequence 3 times per session. Compute the mean for speed and latency; treat any single leak as a failure.
Test Schedule
Tests are conducted monthly across all server regions. Results are updated on corresponding tool, gaming, and streaming pages within 48 hours of completion.
Sample Size
Each server location is tested a minimum of 3 times from at least 2 different source locations. Final metrics are the arithmetic mean of all runs, with outliers (±2σ) discarded.
How to Reproduce Our Results
You can verify our results independently using the same open-source tools. Here is the minimal setup:
