In the case where secured OPC UA client connect to the BMENUA server and IPSEC tunnels are activated to the clients, by default the OPC UA connections will pass inside the tunnel. For the best performances, we recommend configuring the product in order to pass these OPC UA connections outside the tunnel. This can be done as following:

• ADD a new FORWARDING rule,
• Select OPC UA protocol,
• Inbound interface CONTROL PORT or BOTH,
• uncheck IPSEC in use in order to force OPC UA traffic to pass outside the IPSEC tunnel
