Use the "SocketCAN Driver for Linux" from their support page and then you can use any of the CAN-Utils programs: https://github.com/linux-can/can-utils
Any SW engineers in the automotive industry?

For testing I found the CANtact more than adequate. Worked very well with Linux which has the SocketCAN system that basically lets you treat the CAN bus as a network socket. Great tooling exists in can-utils to help you do quick tests, debug a CAN network, and the sniffer is a great help for reverse engineering.

I'm using slcand (to create a "normal" CAN device from SLCAN), candump and cansniffer from the can-utils package on Linux. It is available as a package in Ubuntu, probably also on other distributions. https://github.com/linux-can/can-utils

How you connect to your modem will depend on the device you are using, but for windows laptops as an example you download the OpenVPN program and input your modem details there, much like you would any other vpn service. I think there would be some guides on youtube. https://openvpn.net/
Can i use PFSense to control incoming user connections (without a vpn?)

I just started playing with CloudConnexa for remotely managing my second pFSense. Really nice and is free for up to 3 concurrent users. https://openvpn.net. Can also self-host OpenVPN access server with a free 2 concurrent license.

It is likely an issue with the 'cipher' options, if any, that are in your ".opvn" file. This is telling you that the opvn setting is not finding a matching cipher it is allowed to use. The fix per the message would be to add the Servers cipher to your options. https://github.com/OpenVPN/openvpn-gui/issues/381 https://github.com/OpenVPN/openvpn/blob/master/doc/man-sections/cipher-negotiation.rst
Is it possible for a sysadmin to block only some packets from a VPN connection ?
1 project | /r/OpenVPN | 29 Apr 2023

I too haven't used the client-nat directive in some years (I currently implement 1:1 NAT with pfsense to access my network because I'm too lazy to change the networks subnet from the default) so I decided to retest and it does appear that OpenVPN Connect clients do not properly support the client-nat directive but the traditional OpenVPN server/clients still do. I've just tested this on OpenVPN 2.6.3 Server, OpenVPN 2.6.1 GUI for Windows from openvpn.net, and OpenVPN Connect iOS 3.3.3 and only the OpenVPN Connect client has any difficulty. Difficulty being that you can use client-nat successfully but it has to be configured server-side it can't be pushed to or setup on the client (OpenVPN Connect) side. The Server and Windows (non-OpenVPN Connect) clients work an any setup whether it's configured server-side, pushed to the client, or set up in the client config.

OpenVPN is a VPN client that I used primarily for work. We used VPN to connect to the dev server and we are using VPN. I also sometimes used that to open websites that got blocked in Indonesia like Reddit.
