1. Download prerequisites in a different machine which has access to internet.
2. Move that to the actual server where SharePoint needs to be deployed.
3. Use prerequisite installer to use local folder for installing the prerequisite.

Downloading prerequisites

We can download prerequisites using Powershell. Please use the following script.

Import-Module BitsTransfer
## Prompt for the destination path
$DestPath = Read-Host -Prompt "- Enter the destination path for downloaded files"
## Check that the path entered is valid
If (Test-Path "$DestPath" -Verbose)
{
	## If destination path is valid, create folder if it doesn't already exist
	$DestFolder = "$DestPath\PrerequisiteInstallerFiles"
	New-Item -ItemType Directory $DestFolder -ErrorAction SilentlyContinue
}
Else
{
	Write-Warning " - Destination path appears to be invalid."
	## Pause
	Write-Host " - Please check the path, and try running the script again."
	Write-Host "- Press any key to exit..."
	$null = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
	break
}
## We use the hard-coded URL below, so that we can extract the filename (and use it to get destination filename $DestFileName)
## Note: These URLs are subject to change at Microsoft's discretion - check the permalink next to each if you have trouble downloading.
$UrlList = ("http://download.microsoft.com/download/D/0/F/D0F564A3-6734-470B-9772-AC38B3B6D8C2/dotNetFx45_Full_x86_x64.exe", # Microsoft .NET Framework 4.5

Invoke-Item $DestFolder

 Once all the prerequisites are downloaded, copy them to server in a particular path and create the following batch file.
