Using the AmneziaWG 1.5 Protocol on Self-hosted Servers

Overview​

The new AmneziaWG 1.5 protocol enables VPN traffic to be disguised as common network protocols (e.g., QUIC, DNS, and others), making VPN connections harder to detect and block by Deep Packet Inspection (DPI) systems.

The updated AmneziaWG 1.5 protocol is supported in AmneziaVPN client version 4.8.8.1 and later. No additional server-side configuration is required—your existing server setup is already compatible.

Download the latest client version here:

Important:

  • Exporting configuration via Share with the new AmneziaWG 1.5 parameters is temporarily unavailable and currently under development.

  • A dedicated AmneziaWG application supporting the new protocol is also currently in development.

Quick Start: Traffic Obfuscation as QUIC​

If you want to immediately start using AmneziaWG 1.5 with enhanced protection against DPI, you can apply the recommended configuration by using an obfuscation data packet mimicking the QUIC protocol.

How to Configure​

  1. Open the AmneziaVPN application.

  2. Select your server from the list and click the ⚙️ gear icon to open server settings.

  3. From the list of available servers, select AmneziaWG, and then navigate to the AmneziaWG connection settings section.

  4. Find the field I1 - First special junk packet and paste the following obfuscation packet:

    <b 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>

How to Extract a Protocol Signature for AmneziaWG 1.5 Manually​

This section will guide you through the process of manually finding and extracting a network protocol signature to use with AmneziaWG 1.5.

You will need the Wireshark, application, which can be downloaded from the official website.

Preparation​

  1. Install and launch Wireshark.

  2. In the Wireshark main window, select the network interface currently handling your internet traffic.

  3. Click the Start capturing packets button to begin capturing network traffic.

Finding a Protocol Signature (Using QUIC as an Example)​

Let's illustrate how to find a signature using the popular UDP-based QUIC protocol as an example:

  1. After starting packet capture, enter the name of the desired protocol (e.g., quic) into the Wireshark filter field.

    If you haven't yet selected a specific protocol and want to explore available UDP protocols, simply type udp into the filter field.

  2. From the list of captured packets, select the packet you want to use for obfuscation.

    Tip:
    It's recommended to select initial or final packets from a session, as they tend to be most effective for masking VPN traffic.

  3. Right-click on the selected packet and choose Copy → …as Hex Stream.

    You'll end up with a HEX-formatted string like this:

    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

How to Prepare a HEX String for Use in AmneziaVPN​

After copying the hex string from Wireshark, you need to format it properly to be compatible with the AmneziaWG 1.5 protocol parameters.

To format the hex string correctly, do the following:

  1. Add the prefix <b (with a space) before the string.
  2. Add the prefix 0x immediately before the hex string.
  3. End the string with a closing character >.

Thus, the original hex string: c70000000108ce1bf31eec7d93360000449e227e...
should look like this: <b 0xc70000000108ce1bf31eec7d93360000449e227e...>

Format Explanation:
<b ...> — indicates that this is a special binary data packet.
0x — specifies that the following characters represent hexadecimal (hex) data.

How to Configure​

  1. Open the AmneziaVPN application.

  2. Select your server from the list and click the ⚙️ gear icon to open server settings.

  3. From the list of available servers, select AmneziaWG, and then navigate to the AmneziaWG connection settings section.

  4. Find the field I1 - First special junk packet and paste the formatted string <b 0xHEX>.

  5. Click the Save button to apply the settings.

Your VPN traffic will now be effectively disguised as the chosen network protocol, protecting it from detection by DPI systems.
