There are several ways DPI can detect WireGurad traffic

• The handshake initiation, response and cookie message have fixed sizes
• All messages have 4 byte tag where the first byte indicates message type [1-4] and remaining three bytes are zeroes.
• Handshake packet header contains sender and receiver indexes which are sent unencrypted and can be tracked.

Packet is obfuscated using two techniques

• Random junk bytes are appended to handshake and cookie packets
• Packet header is encrypted with blake2s hash of interface public key and random nonce.

$ cd src
$ make DEV=<name>
$ sudo make install

Where is the name of your notWG device. You can choose almost any name (e.g foobar). Do not use 'wireguard' as the name, this will cause conflict with original wireguard driver.
