I am using 4 different VPN servers with dedicated IP's and port forwarding. One server in Montreal and one in Tokyo are running with wireguard connections in ubuntu without any problems. The server in UK stopped to establish connections with wireguard for more than a week, so I had to switch to openvpn. Also the UK server was down for two days. Trust.zone reported network card problems. The fourth server is located in Moscow and makes the biggest trouble. Wireguard also stopped working for about more than a week. Then I switched to openvpn. With openvpn the connections are now always established and broken after a view seconds. Trust.Zone tells, that there is a second connection present. But I have only one connection. So I assume the dedicated IP is sold to multiple users. Conclusion: The dedicated ip with port forwarding is basically cool. But when it is not working, then trust.zone can't fix it, and has no money back, nor giving another ip at another location as replacement.
It was very cheap, but the worst thing was it was unreliable, it would simply drop the connection when you least expected it. Suspiciously, about 2 months before my subscription expired I got an email - a great new update coming soon. They cut off my access to their service 10 days before my subscription expired - I found that really tacky. Moving on to another service.
I paid for a month's of access it seems this was on OpenVPN - The App was beyond small to the degree it was unusable, no exaggeration. They require registration, (have a look at the likes of OVPN, and IVPN for how it should be done for example) I never did get it connected to London! The worst VPN I have ever used without a doubt. If you doubt this have a try yourself.
