Hello Has anyone connected Ignition a Allen Bradley PLC ( SLC and Controllogix) using a 1783-NATR > **[enet-pp011\_-en-p.pdf](https://literature.rockwellautomation.com/idc/groups/literature/documents/pp/enet-pp011_-en-p.pdf)** > > 990.57 KB I have between Ignition and PLC the 1783-NATR, it is correctly configurated , I can ping the PLCs and I can connect to them via RSLINX, but Ignition is not able to connects. Without the NAT 1783 , the connection works correctly. The Pc of Ignition is 192.168.1.80 and the 1783 NAT is configurated like in the picture ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/9/90b421130442da7d5987b824612ea60a8941d9f1.PNG) In the configuration of the device I used the following IP PLC 1 = 169.254.1.46 PLC 2= 169.254.1.47 But ignition remains In the status “Connecting” any suggestion is appreciated Thank you very much Best regards Andrea ---

Is anything being logged into the gateway console? Go to Status -\> Diagnostics -\> Logs and see if there’s anything related to the device connections you’re trying to set up. ---

We’ve got quite a few PLC’s connected through the 1783-NATR, the connection in Ignition is standard and shouldn’t be a problem if all other networking is correct. It is really important that the PLC has it’s gateway setup properly. You seem to have 3 networks in play here, 192.168, 169.254 and 172.20, do you have routing between them via a gateway? We usually only have two networks when working with the NATR. Are you pinging and connecting via RSLinx from the Ignition server itself? ---

Any time you encounter an IP address of the form 169.254.x.y, you almost certainly have a misconfigured network. These addresses are reserved for automatic addressing in the absence of any DHCP or BOOTP services. See the explanation of [Link Local addresses](https://en.wikipedia.org/wiki/Link-local_address) on wikipedia. Since these addresses can be different at every boot, you must never hard-code them anywhere. ---

Hi I fixed!! The issue was a network route rules problem Thank you very much Best regards Andrea ---

I’m having a similar issue. Assuming the network route rules was a setting in the NAT itself? ---

Hi Andrea. Would you share how you connected ignition to your plc thru the NATR please? ---
