I did something really stupid by accidently.
Well, we have some remote machines running ubuntu 14.04 lts. Those are some kind of servers, not desktop etc.
We can access those servers with port forwarding, and only 443,22,80 ports are enabled. We had some troubles about VPN connections and i connected to a remote with ssh, and then tried to enable ufw rules and then allowed 443 port on that remote, closed and after secs i realized i did something stupid.
Now, i cannot even ssh to fix this problem, i cannot even connect http server of it, and also we already have some problems about port 443, so i cannot find any way to connect this remote. ufw caused to lose connections in any way.
Is there anything i can do to change this stupid mistake. any chance?
