Troubleshooting Windows 11 (23H2): Accessing the Internet via SSH using IPv6

This article aims to help users who are trying to make their Windows 11 (23H2) computer accessible via SSH using IPv6. Unfortunately, nothing tried so far has worked. In this guide, we will cover the key concepts, provide detailed context on the topic, and offer solutions to common issues.

Prerequisites

• A computer running Windows 11 (23H2)
• An IPv6 address
• SSH client and server software (e.g., OpenSSH)

Step 1: Check IPv6 Configuration

First, ensure that your Windows 11 (23H2) computer has a valid IPv6 address. To do this, open the Command Prompt and run the following command:

Look for the IPv6 address assigned to your network interface. If you don't have an IPv6 address, you may need to enable IPv6 on your network connection or contact your network administrator.

Step 2: Install OpenSSH Server

To enable SSH access on your Windows 11 (23H2) computer, you need to install the OpenSSH server. You can do this using the following PowerShell command:

Once installed, start the OpenSSH server using the following command:

Step 3: Configure OpenSSH Server

After installing and starting the OpenSSH server, you need to configure it to listen on your IPv6 address. Open the configuration file with the following command:

Add or modify the following line to include your IPv6 address:

Save and close the configuration file, then restart the OpenSSH server using the following command:

Step 4: Test SSH Access

Now, try to connect to your Windows 11 (23H2) computer using an SSH client. Use your IPv6 address and the default SSH port (22). If you can't connect, check the SSH server logs for error messages.

Common Issues

• Firewall blocking SSH connections: Ensure that your firewall allows incoming SSH connections on your IPv6 address.
• Incorrect IPv6 address: Double-check your IPv6 address to ensure it's correct.
• SSH server not running: Make sure the OpenSSH server is running and configured to listen on your IPv6 address.
