Hi, I'm IT at an engineering company and I've been asked by our Automation department to provide a VPN connection from another company into our company so that they can connect to a Rockwell PLC on our premises. This all for testing and setup purposes so it will be switched on for testing then disconnected afterwards so a super secure industrial solution isn't necessary in this instance. We have a spare internet connection with a fixed IP into our premises.
I have never setup a VPN before so I'm floundering a bit. What I would like is a standalone VPN device connected to our internet router that will provide an ipsec connection that will magically connect to the PLC which has a fixed IP. I understand I'll need to setup port forwarding on the internet router which is just a Huawei HG659 but I really don't understand what VPN device I will need. It needs to be standalone because there won't be a PC between it and the PLC so the device has to do it all.
Where do I start please?
