Hi HMS support,
I recently ran into some trouble connecting a device with an OPC-UA server running on this device. The problem here is that no stable connection can be made that doesn’t time-out in a few minutes.
The situation is that the OPC-UA server has to be connected to an existing wifi network and the wireless bolt has to forward the IP of the machine. Only 1 device is connected to the wireless bolt.
The first setup that I have tried is to setup the wireless bolt to forward the ip-address (Layer 3). Also the bolt was setup to DHCP and the machine to a static IP. The result was quite promising because it was possible to reach the machine using a OPC UA client. But now the problem arises when no connection was set-up to the wireless bolt for a few minutes. The machine then doesn’t connect to the network anymore whilst the wireless bolt is still connected and reachable using a ping tool. A quick fix for the problem is to re-enter the static IP of the machine in the machine interface. I have checked that the IP address for the machine is free and it is (also not in DHCP range).
Am I missing something, what could be the problem in this setup? Firewall?
The second setup I tried is to set up the bolt in MAC forwarding (layer 2) but this isn’t what I want because the OPC UA server is IP and higher level defined so by simply cloning the mac address the server is not reachable.
Wireless bolt version is: 1.6.3 [15:19:00,Aug 28 2018]
Right now I’m stuck and out of ideas, any help on the problem will be very much appreciated. And I look forward to a hearing from you!
