## Host Connection Share
If you connect to the unit via `usb0` (thus using the data port), you might want to use the `scripts/linux_connection_share.sh` or `scripts/macos_connection_share.sh` script to bring the interface up on your end and share internet connectivity from another interface, so you can update the unit and generally download things from the internet on it. Note this script takes as inputs the two interfaces and shouldn't be run without arguments.

.SYNOPSIS
A script that setups Internet Connection Sharing for Pwnagotchi.
.DESCRIPTION
A script that setups Internet Connection Sharing for Pwnagotchi.
Note: Internet Connection Sharing on Windows can be a bit unstable on windows between reboots.
You might need to run this script occasionally to disable and re-enable Internet Connection Sharing.
.PARAMETER EnableInternetConnectionSharing
Enable Internet Connection Sharing
.PARAMETER DisableInternetConnectionSharing
Disable Internet Connection Sharing
.PARAMETER SetPwnagotchiSubnet
Change the Internet Connection Sharing subnet to the Pwnagotchi. Defaults to 10.0.0.1.
.PARAMETER ScopeAddress
Custom ScopeAddress (The IP Address of the USB Gadget Interface.)
.EXAMPLE
# Enable Internet Connection Sharing
PS C:\> .\win_connection_share -EnableInternetConnectionSharing
.EXAMPLE
# Disable Internet Connection Sharing
PS C:\> .\win_connection_share -DisableInternetConnectionSharing
.EXAMPLE
# Change the regkeys of Internet Connection Sharing to the Pwnagotchi Subnet
PS C:\> .\win_connection_share -SetPwnagotchiSubnet
.EXAMPLE
# Change the regkeys of Internet Connection Sharing to the Pwnagotchi Subnet with a custom ScopeAddress (The IP Address of the USB Gadget Interface.)

# Load helper functions
Function Create-HNetObjects {
<#
.SYNOPSIS
A helper function that does the heavy lifiting with NetCfg.HNetShare
.DESCRIPTION
A helper function that does the heavy lifiting with NetCfg.HNetShare. This returns a PSObject containing the `INetSharingConfigurationForINetConnection` info of 2 Adapters.
By default it tries to get the correct interfaces. This method might not be foolproof for every setup, but should work in most default senarios, if this causes issues these
could be passed as a param, they would need to be implemented in Setup-PwnagotchiNetwork and the Param block of this file.
.PARAMETER InternetAdaptor
The output of Get-NetAdaptor filtered down to the 'main' uplink interface. Should default to the correct value.
.PARAMETER RNDISGadget
The output of Get-NetAdaptor filtered down to the 'USB Ethernet/RNDIS Gadget' interface. Should default to the correct value.
