text: <s>[INST] Connect to PF drive through a tunnelling Router Summary: How do I connect to a drive through a tunneling router that changes IP I have an Ethernet IP network with a PLC and Drive on a subnet of 10.179.88.xxx. I have to support this remotely and I'm using a secure router that tunnels traffic through a different IP address. My PLC is on the local network as 10.179.88.20, but when I connect remotely, I set up RSLinx to 10.2.23.20 and the router redirects the traffic to the PLC correctly. I can see my drive in linx at (10.2.23.40) but it's actually at 10.179.88.40. This works great for going online with PLC, but when I connect to the drive, it tells me that it mismatches with the project since the IP in the project is different than the one I'm connecting with. Any ideas on how to connect? [/INST] What software are you trying to connect to the drive with? What type of communication adapter is the drive using for integration? Are you using a licensed copy of RSLinx Classic? What type of RSLinx driver are you using? If using DriveExecutive and trying to connect to a 20-COMM-E adapte with RSLinx Classic Lite (non-licensed)r, I'd try a different EtherNet/IP driver (than the one used to connect to the CPU controller); if this fails try using an Ethernet type (not EtherNet/IP) RSLinx driiver and enter the drive's 20-COMM-E IP address manually. If you are running a licensed copy of RSLinx then you could try using a Remote Devices via RSLinx Gateway RSLinx driver; you will have to enter the drive's communication adapter IP address in Server’s IP Address or Hostname location when configuring this type of driver. \\n </s>
