WPKG over VPN

I have configured all computers to have GPO startup script to run this script instead of wpkg-start.bat only if a computer is present on local subnet (C class) and doesn't have an IP belonging to VPN IP pool. I'm running a small OpenVPN client set. All updates to this script or the whole concept are welcome!

Changes

  • VPN VBs script now called within batch file (keeps main WPKG shell window hidden)

More Changes

If you have the wpkg clients installed and if you use the wpkg service, set up a logon delay (3 minutes for example). You can run the check-vpn.vbs script in the domain logon script to determine whether the client is in the local subnet(s) or not. If the Client is in the VPN subnet (errorlevel 1), just stop the WPKG Service. (net stop "WPKG Service". Another possible solution is to add this "workaround batch script" to the regular tasks and run it for example every 10 Minutes.

check-vpn.vbs

strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_NetworkAdapterConfiguration WHERE IPEnabled = True",,48)

Subnet="192.168.10."
IPStart=245
IPEnd=254

For Each adapter in colItems
	If Not IsNull(adapter.IPAddress) Then
		For i = 0 To UBound(adapter.IPAddress)
			IP = CStr(adapter.IPAddress(i))
			Host = CStr(Trim(Replace(IP, Subnet, "")))
			Dots = InStr(Host, ".")		
		
			if Dots = 0 then
				Host = CInt(Host)
				
				if Host >= IPStart and Host <= IPEnd then
					'NO-WPKG: VPN connection present
					Wscript.Quit 1
				else
					'START-WPKG: local network present
					Wscript.Quit 0
				end if
			end if
		Next
	end if
