I'm struggling with setting up a VPN connection to a remote PLC. There are five of us, each with one or two different devices, who need to access the PLC. We had a VPN router but it seems to have stopped working. Apple's discontinuation of PPTP support has complicated its replacement. I'm wondering if we even need VPN. Couldn't we set up a hardware firewall that would only accept traffic from a list of users?
Please Help.
Thanks !
I didn't find the right solution from the internet.
