Hi everyone,

I need to help about RUT 955 NAT protocol. I will extract data from a plc to my server. But I have ip conflict issue.  I tried to use RUT955 for doing NAT to plc's ip.

I tried to use traffic rules and port forwarding options but they didn't work. Only DMZ worked well. But I wanna create traffic rules or port forwarding between server and plc.

Here you can look at to my network topology. I am trying to reach plc from wan. 

PLC Adress : 192.168.100.5

                        255.255.255.0 

             GW:   192.168.100.1

RUT Adress: LAN 192.168.100.1

                       WAN 192.168.90.10

MY PC Adress : 192.168.90.20

                           255.255.255.0

                GW:   192.168.90.10

Hello,

Please set your PC gateway IP to RUT 955 IP to be able to access it's LAN.

Thank you, I did it but I still can't reach to PLC, for this project I am trying to change plc ip address via router. Because I have several PLC which has same ip address. 

I created port forwarding and traffic rules, here you can see.

You could fully disable the firewall and try changing IP then, once you have it in the right subnet - it should work as it supposed to.

To stop firewall: /etc/init.d/firewall stop (execute this in CLI).
