        "content": "Here are step-by-step instructions to allow inbound SSH (port 22) connections in Windows 11. These apply if you\u2019ve installed OpenSSH Server or another SSH server and want to let clients connect remotely.\n\n---\n\n## Prerequisites\n\nMake sure of the following:\n\n1. OpenSSH Server (or your SSH server of choice) is installed on your Windows 11 machine.  \n2. The SSH service is running and configured to listen on port 22.  \n   - You can check this with PowerShell:  \n     `Get-Service -Name sshd` ([learn.microsoft.com](https://learn.microsoft.com/en-us/troubleshoot/windows-server/system-management-components/troubleshoot-openssh-windows-firewall-port22?utm_source=openai))  \n   - Also confirm listening status:  \n     `netstat -an | findstr :22` should show `LISTENING` on port 22 (for both IPv4 `0.0.0.0:22` and IPv6 `:: :22`) ([learn.microsoft.com](https://learn.microsoft.com/en-us/troubleshoot/windows-server/system-management-components/troubleshoot-openssh-windows-firewall-port22?utm_source=openai))  \n\nIf either of those isn\u2019t the case, set up OpenSSH Server first.\n\n---\n\n## Method 1: Using Windows Firewall with Advanced Security (GUI)\n\n1. Open **Start**, type *Windows Security*, and open it.  \n2. Go to **Firewall & network protection**.  \n3. Click **Advanced settings** \u2014 this opens *Windows Defender Firewall with Advanced Security* ([pureinfotech.com](https://pureinfotech.com/open-firewall-port-windows-11/?utm_source=openai)).  \n4. In the left pane, select **Inbound Rules**.  \n5. In the right pane, click **New Rule\u2026**.  \n6. Select **Port** as the rule type, then click **Next**.  \n7. Choose **TCP**, and then \u201cSpecific local ports\u201d \u2192 enter `22`.  \n8. Click **Next**, choose **Allow the connection**.  \n9. On the profile page, select which network profiles this rule applies to: typically **Domain**, **Private**, **Public** \u2014 depending on your security needs.  \n10. Give the rule a name like \u201cOpenSSH Server (SSH)\u201d or something descriptive.  \n11. Finish the wizard. The rule should now appear under Inbound Rules and permit connections to port 22 TCP.  \n\n---\n\n## Method 2: Using PowerShell\n\nYou can create the inbound rule more quickly via PowerShell. Run PowerShell **as Administrator** and execute:\n\n```powershell\nNew-NetFirewallRule -Name \"OpenSSH-Server-In-TCP\" -DisplayName \"OpenSSH Server (SSH)\" -Enabled True -Direction Inbound -Protocol TCP -LocalPort 22 -Action Allow\n```\n\nThis creates a firewall rule named \u201cOpenSSH-Server-In-TCP\u201d to allow incoming TCP connections on port 22. ([learn.microsoft.com](https://learn.microsoft.com/en-us/troubleshoot/windows-server/system-management-components/troubleshoot-openssh-windows-firewall-port22?utm_source=openai))\n\n---\n\n## Method 3: Using Command Prompt with netsh\n\nAlternatively, in an elevated Command Prompt:\n\n```cmd\nnetsh advfirewall firewall add rule name=\"SSH\" dir=in action=allow protocol=TCP localport=22\n```\n\nThis also opens port 22 for incoming SSH traffic. ([pureinfotech.com](https://pureinfotech.com/open-firewall-port-windows-11/?utm_source=openai))\n\n---\n\n## After Opening the Port\n\n- **Confirm the rule** exists:  \n  Use PowerShell:  \n  `Get-NetFirewallRule -DisplayName \"*SSH*\"`  \n  And see if it has a filter with `LocalPort = 22`. ([learn.microsoft.com](https://learn.microsoft.com/en-us/troubleshoot/windows-server/system-management-components/troubleshoot-openssh-windows-firewall-port22?utm_source=openai))\n\n- **Ensure sshd is running**:  \n  `Get-Service -Name sshd` \u2192 if not running, start it:  \n  `Start-Service sshd`  \n\n- **Check sshd configuration** if port 22 is not active. In the file `C:\\ProgramData\\ssh\\sshd_config`, verify that the line `Port 22` is present (not commented out) and correct. Then restart the service via PowerShell:  \n  `Restart-Service sshd` ([learn.microsoft.com](https://learn.microsoft.com/en-us/troubleshoot/windows-server/system-management-components/troubleshoot-openssh-windows-firewall-port22?utm_source=openai))\n\n---\n\n## Security Tips\n\n- Limit the rule to only the network profiles you need (for example, avoid enabling Public unless necessary).  \n- If possible, restrict which remote IPs can connect (some rules allow you to set *RemoteAddress* filters).  \n- Keep your SSH server, Windows updates, and firewall rules current.  \n- Use strong authentication (keys instead of passwords, disable root or admin login if applicable).\n\n---\n\nIf you like, I can walk you through exactly configuring this for your setup (e.g. if you're on a private network, or have an external router/NAT, etc.). Do you want that?"

Run all in a PowerShell window with **Administrator** privileges.\n\n---\n\n## 1. Remove the old rule allowing SSH on port 22\n\nIf you know the **DisplayName** (or **Name**) of the rule you want to delete, use:\n\n```powershell\n# Remove by DisplayName\nRemove-NetFirewallRule -DisplayName \"OpenSSH Server (SSH) Port 22\"\n```\n\nIf you don\u2019t know the exact name but know it's an inbound rule on port 22, you can find then remove it like this:\n\n```powershell\nGet-NetFirewallRule |\n  Get-NetFirewallPortFilter |\n  Where-Object LocalPort -eq 22 |\n  ForEach-Object { \n    # $_ refers to the PortFilter; get the associated rule via:\n    $rule = Get-NetFirewallRule -AssociatedNetFirewallPortFilter $_ \n    Remove-NetFirewallRule -Name $rule.Name\n  }\n```\n\nThis chain:  \n- identifies port filters listening on local port 22,  \n- finds their corresponding firewall rule,  \n- and deletes them.  \n([learn.microsoft.com](https://learn.microsoft.com/es-es/powershell/module/netsecurity/get-netfirewallportfilter?view=windowsserver2025-ps&utm_source=openai))\n\n---\n\n## 2. Add a new rule allowing SSH on port 2022 (TCP, inbound)\n\n```powershell\nNew-NetFirewallRule `\n  -DisplayName \"OpenSSH Server (SSH) Port 2022\" `\n  -Direction Inbound `\n  -Protocol TCP `\n  -LocalPort 2022 `\n  -Action Allow `\n  -Enabled True `\n  -Profile Domain,Private,Public\n```\n\nThis creates a firewall rule named *\"OpenSSH Server (SSH) Port 2022\"* that allows incoming TCP traffic on port 2022 in all network profiles.  \n([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/module/netsecurity/new-netfirewallrule?view=windowsserver2019-ps&utm_source=openai))\n\n---\n\n## 3. Optional \u2013 Use `WhatIf` first\n\nBefore you actually remove anything, you can add `-WhatIf` to the remove command to see what *would* be removed without performing the action:\n\n```powershell\nRemove-NetFirewallRule -DisplayName \"OpenSSH Server (SSH) Port 22\" -WhatIf\n```\n\n---\n\n## Summary\n\nIn short:\n\n- **Delete** the old port 22 rule using `Remove-NetFirewallRule` (by name or via port filtering).  \n- **Add** the new port 2022 rule using `New-NetFirewallRule` with the proper parameters.\n\nIf you want help matching *exactly* the name or locating the specific old rule in your setup, I can help you grab that too."

        "content": "To connect your Windows Firewall rule (port 2022 open) with `sshd` running inside WSL on the **default SSH port 22**, you need to forward incoming traffic on Windows port 2022 to WSL\u2019s port 22. Here are the steps:\n\n---\n\n## Steps\n\n1. **Find the WSL 2 VM\u2019s IP address**  \n   From inside your WSL distro, run:\n   ```bash\n   hostname -I\n   ```\n   This gives you the IP address (e.g. `172.22.15.100`). ([docs.nvidia.com](https://docs.nvidia.com/nim/wsl2/1.0.0/running-client-port-forwarding.html?utm_source=openai))\n\n2. **Set up port forwarding using netsh on Windows**  \n   Open PowerShell **as Administrator**, then run:\n\n   ```powershell\n   netsh interface portproxy add v4tov4 `\n     listenport=2022 listenaddress=0.0.0.0 `\n     connectport=22 connectaddress=<WSL_IP>\n   ```\n\n   Replace `<WSL_IP>` with the IP you got in step 1. This redirects all TCP traffic arriving on Windows port 2022 to port 22 inside WSL. ([docs.nvidia.com](https://docs.nvidia.com/nim/wsl2/1.0.0/running-client-port-forwarding.html?utm_source=openai))\n\n3. **Ensure firewall allows on port 2022** *(you\u2019ve already done this)*  \n   Just confirming: you need a firewall rule to allow inbound TCP on port 2022. Sounds like that\u2019s set. ([learn.arm.com](https://learn.arm.com/learning-paths/laptops-and-desktops/wsl2/ssh/?utm_source=openai))\n\n4. **Connect via SSH using Windows address and port 2022**  \n   From another device (or locally), you can connect like:\n\n   ```\n   ssh user@<Windows_IP_or_Hostname> -p 2022\n   ```\n\n   - If connecting from the same Windows machine:  \n     `ssh user@localhost -p 2022`\n   - If connecting from another machine on your LAN:  \n     Use the LAN IP of your Windows host, e.g. `ssh user@192.168.1.50 -p 2022`. ([learn.arm.com](https://learn.arm.com/learning-paths/laptops-and-desktops/wsl2/ssh/?utm_source=openai))\n\n---\n\n## Notes & Gotchas\n\n- WSL 2\u2019s IP typically changes after you **reboot WSL** or restart the host OS. If that happens, the `netsh interface portproxy` rule keeps forwarding to the old address and stops working. You\u2019ll have to update it to the new WSL IP. ([docs.nvidia.com](https://docs.nvidia.com/nim/wsl2/1.0.0/running-client-port-forwarding.html?utm_source=openai))\n\n- If your Windows host is running a firewall beyond just Windows Defender, or using any security solution with its own network firewall, ensure port 2022 is allowed there too.\n\n- If `sshd` inside WSL is bound only to `localhost (127.0.0.1)` by default, you may need to configure it to also bind to its WSL IP or `0.0.0.0`. That\u2019s in `/etc/ssh/sshd_config` under `ListenAddress`. Restart the SSH service after making changes. ([learn.arm.com](https://learn.arm.com/learning-paths/laptops-and-desktops/wsl2/ssh/?utm_source=openai))\n\n---\n\nIf you want, I can give you a script to automate updating the portproxy whenever WSL\u2019s IP changes. Do you want that?"

After that, you\u2019ll be running `sshd` inside WSL so you can accept SSH connections (for example using the port forwarding you set up earlier).\n\n---\n\n## Steps to Install OpenSSH Server on Debian 13 (WSL)\n\nOpen a WSL terminal for the Debian 13 distro and run the following commands:\n\n1. Update package metadata and upgrade existing packages:\n\n   ```bash\n   sudo apt update\n   sudo apt upgrade -y\n   ```\n\n2. Install the OpenSSH server package:\n\n   ```bash\n   sudo apt install openssh-server -y\n   ```\n\n   This will also pull in any necessary dependencies. ([rosehosting.com](https://www.rosehosting.com/blog/how-to-enable-ssh-on-debian-13/?utm_source=openai))\n\n3. Make sure the SSH service (`ssh.service`) is enabled and started.\n\n   ```bash\n   sudo systemctl enable ssh --now\n   ```\n\n   Check status:\n\n   ```bash\n   sudo systemctl status ssh\n   ```\n\n   You should see output indicating **Active: running**. ([linuxcapable.com](https://linuxcapable.com/how-to-install-ssh-and-enable-on-debian/?utm_source=openai))\n\n---\n\n## Configure OpenSSH (if needed)\n\nAfter installation, there are a few things you might want to configure to make sure SSH works as you expect inside WSL.\n\n4. Edit `/etc/ssh/sshd_config` to customize settings. For example:\n\n   - Change the port if you want (this defaults to 22).\n   - Ensure `ListenAddress` is set to either `0.0.0.0` or the WSL VM\u2019s internal IP, not just `localhost`, so port forwarding from Windows can reach it.  \n   - You may want to disable root login, enforce public-key authentication, etc. ([tecadmin.net](https://tecadmin.net/install-update-openssh-on-debian/?utm_source=openai))\n\n   After making changes, test the config:\n\n   ```bash\n   sudo sshd -t\n   ```\n\n   Then restart:\n\n   ```bash\n   sudo systemctl restart ssh\n   ```\n\n---\n\n## Common Pitfalls in WSL\n\n- **No systemd by default**: WSL distros don\u2019t always support systemd. If your Debian 13 WSL doesn\u2019t have systemd, `systemctl` commands may not work. In that case you\u2019ll need to start `sshd` manually:  \n  ```bash\n  sudo /usr/sbin/sshd\n  ```\n\n- **Persisting changes**: If you restart WSL or your machine, systemd-less setups or manually started daemons won\u2019t auto-start. You\u2019ll need to run `sshd` each time or use some workaround (like a script that starts it on login).\n\n---\n\nIf you want, I can give you exactly the configuration file tweaks needed for WSL + port forwarding setup (e.g. matching your Windows port 2022 \u2192 WSL port 22)."
