Accessing WireGuard VPN via UDP2 Raw SHH Tunnel on Raspberry Pi
In this article, we will discuss how to access a WireGuard VPN server running on a Raspberry Pi 5 from a remote location using the UDP2 Raw SHH tunnel. This method is particularly useful when you are unable to access the WireGuard VPN server directly from a restricted network, such as a school or public Wi-Fi network.
Prerequisites
Before we begin, ensure that you have the following:
- A Raspberry Pi 5 running the latest version of Raspberry Pi OS.
- WireGuard VPN server set up and running on the Raspberry Pi.
- SSH access to the Raspberry Pi from the remote location.
Setting up the UDP2 Raw SHH Tunnel
To set up the UDP2 Raw SHH tunnel, follow these steps:
- Connect to the Raspberry Pi via SSH from the remote location.
- Create a new file named "udp2raw.service" in the "/etc/systemd/system" directory:
sudo nano /etc/systemd/system/udp2raw.service
Add the following content to the file:
[Unit]
Description=UDP2 Raw SHH Tunnel
After=network.target
[Service]
User=root
ExecStart=/usr/bin/udp2raw -s :5353 -d :51820 -c 512 -l 0.0.0.0
Restart=always
[Install]
WantedBy=multi-user.target
Save and close the file.
- Enable and start the UDP2 Raw SHH service:
sudo systemctl enable udp2raw
sudo systemctl start udp2raw
Using the UDP2 Raw SHH Tunnel with WireGuard
To use the UDP2 Raw SHH tunnel with WireGuard, follow these steps:
- Create a new WireGuard interface configuration file on the remote device:
sudo nano /etc/wireguard/wg0.conf
Add the following content to the file:
[Interface]
Address = /32
PrivateKey =
ListenPort = 51820
[Peer]
PublicKey =
Endpoint = :5353
AllowedIPs = 0.0.0.0/0
PersistentKeepalive = 25
Replace the following:
- Start the WireGuard interface:
sudo wg-quick up wg0
