Try something like this:
code:
$HKLM = "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services"
$Index = 0
:Loop1
$KeyName = ENUMKEY( "$HKLM\Class\NetTrans\" , $Index )
$RC = @ERROR
$Index = $Index + 1
$Gateway=ReadValue("$HKLM\Class\NetTrans\$KeyName","DefaultGateway")
If $Gateway = "YourCurrentGateway"
		;$ReturnCode = WRITEVALUE( "$HKLM\Class\NetTrans\$KeyName" , "IPAddress" , "0.0.0.0" , "REG_SZ")
		;$ReturnCode = WRITEVALUE( "$HKLM\Class\NetTrans\$KeyName" , "IPMask" , "0.0.0.0" , "REG_SZ")
		$ReturnCode = WRITEVALUE( "$HKLM\Class\NetTrans\$KeyName" , "DefaultGateway", "0.0.0.0" , "REG_SZ")
EndIf
goto Loop1
