AWS Lightsail and the Telnyx Network
Here's an overview of what we will be going over:
Deploying a Ubuntu 20.04 Lightsail VPS (or your preffered distribution)
Installing WireGuard on the VPS
Configuring WireGuard with Telnyx on the VPS
Step 1: Configuring for Telnyx
Reference the introduction to Telnyx Networking section located here: Telnyx Configuration
Copy and take note of the Peer Configuration file along with the private key that you got assigned from the above tutorial, it should look like the following:
Step 2: Deploy an Amazon Lightsail VPS
Log in to Amazon Lightsail and click on "Create instance."
Choose a location by clicking on "Change AWS Region and Availability Zone."
Select "Linux/Unix" and choose "Ubuntu 20.04 LTS" as the operating system.
Give the instance a name and click "Create instance."
Take note of the public IP address of the instance as you will need it later for SSH connection and configuring the WireGuard VPN client.
Step 3: Configuring Networking
Now that your instance is running, you need to make some changes to the firewall rules to allow WireGuard clients to connect to the server.
Click on the instance name and go to the "Networking" section.
Delete the HTTP rule (since it's not a web server) by clicking on the recycle bin icon next to the HTTP rule.
assign port 51820
This port will be used by the WireGuard service to connect to clients.
Step 4: Connecting to the VPS Instance with SSH
Now it's time to establish an SSH connection to your VPS instance.
Navigate to the "Account" section, then click on "SSH keys.
Download the key assigned to your instance and save it on your computer.
Open a Terminal session (Unix-like operating systems) or Putty (Windows).
Make the key readable only by the current user:
chmod 600 ~/Desktop/vpn.cer
Connect to the VPS instance using the public IP address and the certificate path:
ssh -i ~/Desktop/vpn.cer ubuntu@[PUBLIC_IP_ADDRESS]
Step 5: Enabling Port Forwarding
After connecting to the server, the next step is to enable port forwarding so that client traffic can access the internet.
Enable port forwarding by creating a file called
"10-wireguard.conf" in the
sudo vim /etc/sysctl.d/10-wireguard.conf
Add the following contents to the file:
To enable port forwarding immediately, run the command:
sudo sysctl -p /etc/sysctl.d/10-wireguard.conf
Step 6: Installing WireGuard and Generating Keys
Install WireGuard by running:
sudo apt update && sudo apt install wireguard -y
Generate the server and client keys using the following commands:
wg genkey | tee server.key | wg pubkey > server.pub
wg genkey | tee client.key | wg pubkey > client.pub
A list of files should now be created
/etc/wireguard# ls -ltotal 16
-rw------- 1 root root 45 Jun 29 10:32 client.key
-rw------- 1 root root 45 Jun 29 10:32 client.pub
-rw------- 1 root root 45 Jun 29 10:32 server.key
-rw------- 1 root root 45 Jun 29 10:32 server.pub
Step 7: Creating the WireGuard Server Configuration
We now need to create the config file for the WireGuard service before we start it
sudo vim wg0.conf
We can now copy/paste our configuration files we got from Step 1 inside here, from the Telnyx portal:
To enable the service when the server boots, simply run:
sudo systemctl enable wg-quick@wg0
To start the service now run:
sudo systemctl start wg-quick@wg0
Step 8: Test
We can test to see if it's working by checking the portal and seeing the last seen status change:
or you can curl/trace into your server to confirm the Global IP that is configured to it.
