Installing StrongSwan on macOS

StrongSwan is an open-source IPsec-based VPN solution that provides seamless and secure communication between networks. In this tutorial, we will go through the steps to install StrongSwan on macOS.

Prerequisites

Step 1: Install Homebrew

If Homebrew is not already installed on your machine, this can be done by running the following command in your terminal:

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Step 2: Install Xcode or Command Line Tools

If Xcode or Command Line Tools are not already installed on your machine, this can be done by running the following command in your terminal:

$ xcode-select --install

Step 3: Install the StrongSwan package

Once Homebrew, Xcode or Command Line Tools are installed, we can proceed to install StrongSwan by running the following command in your terminal:

$ brew install strongswan

Step 4: Start and enable the StrongSwan service

After installation, we need to start and enable the StrongSwan service to run automatically when the machine starts up. This can be done by running the following command in your terminal:

$ sudo brew services start strongswan

Step 5: Verify the installation

Once the StrongSwan service is started, we can verify the installation by running the ipsec command in your terminal:

$ ipsec version

This should display the StrongSwan version running on your machine.

Conclusion

We have successfully installed StrongSwan on macOS, and the service is now running and enabled to start automatically on boot. You can now configure the StrongSwan service to create secure VPN connections between networks.
