The need for a reliable, unrestricted, and secure internet connection is constant—and this can’t be separated from the role of VPN protocols. There are many types of VPN protocols, and one of the most well-known is WireGuard. But before diving deeper, it's important to understand what a VPN protocol actually is. In essence, a VPN protocol is a set of rules that governs how data is transmitted and encrypted to ensure a secure internet connection and bypass most geo-based access restrictions.
Again, a VPN protocol is not the same as a VPN brand. A protocol can be used by multiple providers, and WireGuard is one that’s employed by popular VPN services like Surfshark, NordVPN, and Proton VPN. Its modern and lightweight design makes it known for speed and efficiency.
However, the speed and security that WireGuard offers often mean little to users who have one specific goal: bypassing VPN blocks. This is because connections using WireGuard are relatively easy to detect by DPI (Deep Packet Inspection) systems. That’s why WireGuard traffic obfuscation—though not a built-in feature—is considered essential by these users.
Another method is changing WireGuard’s default port. The default port is easily recognized, so switching to more commonly used ports gives a better chance of avoiding detection by public Wi-Fi systems designed to intercept VPN connections based on port signatures.
There’s also the option of encapsulating WireGuard traffic within HTTPS, making it look like harmless regular internet traffic. Some more creative users even go as far as adding junk data into the stream to obscure the “actual important data.”
At its core, there are quite a few methods to obfuscate WireGuard traffic, but the most widely used are the ones mentioned above.
2. Run udp2raw on the Server.
3. Run udp2raw on the Client
4. Finally, configure WireGuard. Use 127.0.0.1:51820 as the endpoint on the client:
Now start WireGuard on both Server and Client and it should work. Your WireGuard traffic is now hidden behind udp2raw’s fake TCP/UDP.

So how does WireGuard obfuscation work?
Essentially, it works by “wrapping WireGuard in a certain layer” so that inspection systems don’t recognize it as a VPN protocol. There are several techniques used to achieve this, but one of the most common is integrating WireGuard with Shadowsocks. This is done by routing WireGuard traffic through a Shadowsocks connection, which makes it appear as standard Shadowsocks traffic. This technique is known as tunneling. Tunneling can also be done using other protocols, such as SSH.Another method is changing WireGuard’s default port.

How to obfuscate WireGuard traffic?
1. Install udp2raw on Server and Client.
Code:
wget https://github.com/wangyu-/udp2raw/releases/latest/download/udp2raw_binaries.tar.gz
tar -xvzf udp2raw_binaries.tar.gz
cd udp2raw_binaries
chmod +x udp2raw_amd642. Run udp2raw on the Server.
Code:
./udp2raw_amd64 -s -l0.0.0.0:4096 -r127.0.0.1:51820 -k "secretkey" --raw-mode faketcp3. Run udp2raw on the Client
Code:
./udp2raw_amd64 -c -r1.2.3.4:4096 -l127.0.0.1:51820 -k "secretkey" --raw-mode faketcp4. Finally, configure WireGuard. Use 127.0.0.1:51820 as the endpoint on the client:
Code:
[Peer]
Endpoint = 127.0.0.1:51820Now start WireGuard on both Server and Client and it should work. Your WireGuard traffic is now hidden behind udp2raw’s fake TCP/UDP.
