OPC-UA WAN side - n.maclean@eandr.com - 07-12-2020

Hello,

I've been experimenting with the OPC-UA server in a Flexy 205 and I can get it to work OK on the LAN side but the setup documentation implies that it should be available on the WAN side.

Guide


On the LAN side, I can connect to opc.tcp://IP_Address:4840. I have tried both WAN address and VPN address but cannot connect to either. Am I missing something?

Hi Nick,

Two things I am thinking about :
- Are you running the latest firmware version 14.3
- Regarding the WAN, have you unprotected it ? You need to set the WAN protection level to "Allow all" (and reboot the Ewon)

Hi Simon,

Thanks for your reply. The device I'm testing is on Firmware 14.2 so I can update that as it is attached to an R&D machine. As for the "Allow All" option, I did look at that and it wouldn't be my first choice for security reasons but may worth considering.

If you want to make the OPCUA Server accessible over the WAN port, it is mandatory to set it to "Allow all".
