Dear Ignition team,
I have to establish a OPC-UA connectivity between 2 ignition gateways
1) Ignition OPC UA Server running on OT network(Yokogawa DCS network)
2) Ignition OPC UA Client running on IT network
3) These 2 gateways will be connected through firewall
I have few question about above configuration
1) What are the port numbers I should allow through firewall?
2) IP address class is different for IT and OT network, in this case what specific action I should perform?
Included the system architecture here:
