my project setup is as follows: PLC \> IIoT Gateway \> OPC UA \> Ignition gateway \> Perspective. the IIoT gateway and Ignition gateway are on different networks. The IIoT acts as OPC UA server sending all data tags to ignition gateway. I need to connect IIoT gateway and Ignition gateway in order to receive the tags data. is it possible? ---

If you are saying the IIoT Gateway as in the [Edge IIoT](https://www.docs.inductiveautomation.com/docs/8.1/other-editions/ignition-edge/edge-iiot) Then yes this is possible by using the GAN and setting up remote tag providers. The documentation is available in the link above. ---

OPC UA is a fully routable TCP-based protocol (in the IA implementation). So, yes. No GAN required. ---

Thanks for the clarification. Could be please elaborate more on how to make connect to OPC UA from another network? Does it mean I need to use VPN or there's another way? ---

If there's not some sort of route for the connections between the 2 networks currently, yes, you'll need some sort of VPN to connect the 2 networks. ---

will port forwarding be useful in this case or it is less secure? ---

If you're port forwarding, you're really opening up a security hole. Essentially allowing anyone on the internet to access your data. Unless you're using certificates for security, it probably won't be long until you have unwanted bots/systems trying to get into your system. Definitely try to keep it secured behind a VPN if possible. ---
