Hi
The LPUF board is an interface board. No license is required for board insertion. Only related software features require a license.
Version: V6R7 and earlier versions: The L2TP function is supported only by the LPUF-21-E and LPUF-40-E boards.
Version: V6R8 and later versions: LPUF-51/LPUI-51-E, LPUF/I-101/120, and LPUF/I-240 are added.
