First of all, thank you for your reply, mkx.
Only one device on every subnet will be connected.
If I understood correctly, I have to do the following steps:
- Create addresses on both Ethernet devices, I will do that on Ethernet ports.
- Configure the router to perform SRC-NAT from PC towards IoT.
Please confirm I got your instructions the wa you meant them.
What I did not understand is " … whether those devices can use router as their default gateway or not". Can you please explain what do you mean?
