Good morning everyone,

Im working on a project that involves setting up at redundant S7-1500R/H station with two 1517H-3 PN CPU. I also have one CP 1543-1 on each of the CPU's. A quick overview of the topology is that interface X2 on both CPU is connected to the engineering subnet (192.168.1.X). Interface X1 is connected to distributed I/O subnet (192.168.0.X). The CP153-1 is connected to the X1 interface of the HMI with same subnet as I/O (192.168.0.X) and the X2 on HMI is connected to the engineering subnet (192.168.1.X)

My question regarding IP forwarding is simply that i wanna connect from engineering interface X2 into the subnet connected on X1, and preferably the subnet on the CP1543-1. I have actived the "Enable IPv4 forwarding for interfaces of this PLC" but no luck so far. Anybody with some experience on this matter that can help me?

My other questions is regarding SNMPv3. Im not sure if the 1517H-3 supports v3, but i know the CP1543-1 supports it. I have activated it in security functions, but where do i set up users, encryption and so on for the v3 authentication in TIA 19? Its quite straightforward on for example Scalance X switches.

Any help or tips is appreciated!

Have a nice day!
