# Localhost
|
|
|
|
`localhost` is a WSL2 linux process, created by [mini_init](mini_init.md). Its role is to forward network traffic between the WSL2 virtual machine, and Windows.

|
## NAT networking
|
|
|
|
When `wsl2.networkingMode` is set to NAT, `localhost` will watch for bound TCP ports, and relay the network traffic to Windows via [wslrelay.exe](wslrelay.exe.md)
|
|
|
|
## Mirrored networking
|
|
|
|
In mirrored mode, `localhost` registers a BPF program to intercept calls to `bind()`, and forward the calls to Windows via [wslservice.exe](wslservice.exe.md) so Windows can route the network traffic directly to the WSL2 virtual machine.
