Hi everyone.

I’m trying to configure and test IPsec Strongswan on my ubuntu machine. I’ve created my-vpn.conf file and added
local_ts = 10.0.0.0/24 # Traffic selector for local network
remote_ts = 10.0.1.0/24 # Traffic selector for remote network.

Now I’m trying to set up a opc ua server. As far as i understand, i have to add an Endpoint that will listen on remote_ts address and set 4840 port, so the server’s url would look like opc.tcp://10.0.1.1:4840.

Is it possible and if so, how can i do that?

Hi,

You posted this in the generic forum, not in https://forum.prosysopc.com/forum/opc-ua-simulation-server/, but based on your wording I’m going to assume you still mean our https://prosysopc.com/products/opc-ua-simulation-server/ application.

Did you already just try connecting? What didn’t work?

In short, there is no support for adding additional endpoints, but also there is no need to do that. They sort of have “nothing do with connections” and can more be though to be historical details (If you run more than one OPC UA server in the same port, client chooses with this the one which the traffic is routed). In OPC UA in general most applications just have a single EndpointUrl that uses the machines hostname, but they still do listen to multiple interfaces for that endpoint. The Simulation Server by default binds to all interfaces via the wildcard ip address “0.0.0.0” or “[::]” thus as long as the traffic reaches one, everything should work. Try e.g. testing with https://prosysopc.com/products/opc-ua-browser/ from the other end.

P.S.
https://prosysopc.com/blog/opc-ua-wireshark/ might help for figuring out does the traffic reach the interfaces, but in general we cannot debug your vpn if that doesn’t happen.
