controllogix MSG with NAT'd out Stratix

I have 2 identical machines and need to read bits from one in the other. By identical I mean they are the same physically and in IP structure. They both have the same private IP address and use a Stratix 5700 to NAT out the private IP into a public IP for the plant network:

Machine------Private IP--------Public IP
1-----------10.14.230.1-------10.14.220.153
2-----------10.14.230.1-------10.14.220.161
3-----------10.14.230.1-------10.14.220.169
Stratix------Private IP--------Public IP
1-----------10.14.230.5-------10.14.220.158
2-----------10.14.230.5-------10.14.220.166
3-----------10.14.230.5-------10.14.220.174


What I need to figure out is the comms path for the message instruction, "1, 0, 10.14.220.166, 1, 0" is what I have tried, but I get an error saying the module could not be found. Has anyone dealt with this scenario before, I am not finding anything in the knowledge base dealing with NAT'd out MSG instructions, and my techconnect contract is only good M-F.

Thanks
Ian

oops, turns out the reason it didn't work was because the Stratix switch had broken and was replaced and not yet setup, after that all I needed in the connection path was "2, destination public ip"

Hi Ian762

I have the same problem what was the answer for the problem. That i can see you only change the path?. Can you explain more please? Thank you very much

My issue was that the Stratix switch was not configured, so there was no NAT happening. After I configured the switch and setup the NAT tables, I was able to communicate between the PLC's.


I was also using the wrong syntax in my message communication path. I was using "1, 0, 10.14.220.166, 1, 0", when I needed to use "2, 10.14.220.166" b/c I was using CompactLogix PLC's.

Thank you very much for your fast response
