IIoT gateway and Ignition gateway

Ignition
1

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

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.

"Won't be long" in this case is a range of seconds to minutes. Be extremely cautious exposing anything to the wide open Internet.
