Allow WSL2 To Connect To The Outside World

1

If you are running WSL2 on Windows 11 22H2 or higher, you can now use mirrored mode networking.

In your %USERPROFILE%\.wslconfig file in Windows (create it if it doesn't exist), add the line networkingMode=mirrored under [wsl2].

Allow inbound connections through the Hyper-V firewall. This can be done by running one of the following commands in PowerShell with administrator privileges.

One port or range of ports: 
```New-NetFirewallHyperVRule -DisplayName "WSL SSH" -Direction Inbound -VMCreatorId "{40E0AC32-46A5-438A-A0B2-2B479E8F2E90}" -Protocol TCP -LocalPorts 22```
 
Change -DisplayName to your desired value and -LocalPorts to your desired port or range of ports

All ports: 

```Set-NetFirewallHyperVVMSetting -Name "{40E0AC32-46A5-438A-A0B2-2B479E8F2E90}" -DefaultInboundAction Allow```

Run WSL with the new config, for example using wsl --shutdown and then wsl to restart it.

This should be enough to allow connections to sshd and other WSL-hosted servers over LAN.
