To enable [IP forwarding](https://support.industry.siemens.com/cs/ww/en/view/109815056/161008725899 "'IP forwarding' in system manual 'STEP 7 and WinCC Engineering V18'") you need a S7-1500 V2.8 or higher and:
- A CPU with at least two Ethernet interfaces.
- Or a CPU with one Ethernet interface and a CP 1543-1 with firmware version V2.2 or higher providing the other Ethernet interface. In this case the function "Access to PLC via communication module" must be enabled for the CP in the CPU.
So it is ==unfortunately not supported for SIMATIC ET 200SP CPUs==, expect the new CPU 1514SP-2.
