I want to start by saying that I am fairly new to ICT/IoT, couldn't find more info about this problem so here I go.
I'm using Teltonika RUT955/950 with 06.06.1 FW with my CentOS 8 OVPN-server. I have succesfully connected and routed the tunnel so there's no problem. One thing I found weird and really cannot find an explanation is that why tun0, tun1, tun2 and tun3 are connected to hotspot? Isn't tun0 etc. the default interface/device for ovpn tunnels? The problem occurs when I use my pre-made client config, not the GUI client setup (Names it differently, tun_c_client1 for example). Using the pre-made client config, with the tun0 interface my RUT955 thinks it is a hotspot connection and my/pre-configured (SSH/HTTP) traffic rules don't work the way I want them to. I can easily go around the problem using hotspot as the source, but that really isn't a fix.
Really appericiate any help or explanation!
