Well, it kind of works for me, but only for couple of seconds (about 15). I used installation trough Foris. I extracted certs and keys from downloaded configuration file and created VPN configuration manually trough GUI in Ubuntu. Then, I was able to connect and ping my NAS at 192.168.0.147. But after few seconds it stopped working. I disconnected from VPN and connect again. It started working but after another couple of seconds it failed again. I have no idea why is this happening.

Lokální síť mám 192.168.0.0/24 a při generování configurace VPN jsem nastavil 192.168.1.0/24. To je předpokládám správně, když se mi to alespoň na chvíli připojí.
Připojení na mobilu mi ale drží.
