My currently VPN setup and goal was too configure and manage both machines
talking to each other while using TINC. yES! i WAS SUCCESSFUL in connecting
and establishing MY OWN vpn remotely. I had to read a lot on ths tinc website
and following their guidance and help examples, was available to you to read
all about it. I READ and download all the information , i need to know on
https://www.tinc-vpn.org/.
Yes, I use trsquel 9 and ONE debian machine. it is a GPL license project.
It worked for me. kNOW i HAVE MY OWN VPN ESTABLISHED.
