I will try the tcpdump. Only the CLI is not working, I have enabled it in access control. But it gives a time out. So I try putty now. An other problem is. The support side is in France and my company is in the Netherland. The communication is not going that smooth, but I will try.
I don’t know of the equipment has a standard gateway configured. That is also done by the people in France. Do we need a gate way? Do we need NAT?
I am not an expert in VPN and routing, sorry for that.
When I was looking at the configuration of the LAN interface i found it was in bridge mode.
This bridges the LTE data connection with LAN. I think we won’t have that, it also disable most of the device’s capabilities.
Tomorrow I will arrange a new test with our friend from France.
