So you need remote access to Raspberry Pi. If you have fixed IP addresses at home, ssh that is firewalled to those addresses is easiest.
If you don't have fixed IP addresses, ssh access authenticated only by keys is easy once set up. If you'd like help with that, what operating systems will the remote accessors be using? The link you provided goes to the index of a forum, so it's not clear to me which VPN software you have been trying. If you do go down the VPN route, in my experience OpenVPN is relatively easy to set up, is secure, and it's supported on Windows, Linux, OSX, Android (don't know about iPhone, never used one). Happy to help more, but I would urge "keep it simple". -- Linux Tips: https://www.tiger-computing.co.uk/category/techtips/ -- Next meeting: Online, Jitsi, Tuesday, 2020-07-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
