Hello!
Due to other issues, I need to implement port forwarding between two devices connected to LAN (LAN1<->LAN3) ports. It seems that this doesn’t work with simple port forward rules (probably due to missing or incorrect settings…).
I’d be happy to receive any suggestions from experts more experienced than me (everyone is more experienced than I am 
).
Hello,
Could you please provide more details about your setup? Specifically, what is the goal you are trying to achieve?
It would also be helpful if you could share the network topology along with the IP addresses involved.
Best regards,
This is the network topology. The green works, the red does not.
On DEVICE1 runs both Modbus TCP master and slave simultaneously. Since by default both Modbus actors would use port 502, this (likely) causes the DEVICE1 to freeze randomly, so I am trying to use a different port on DEVICE1 (on DEVICE2 cannot be adjusted).
Could you please also share the port forwarding rules you created?
Best regards,
