Unable to enable firewall on Orange PI PC

zamana

Hi!

It doesn't matter which "distro" I put on my Orange PI PC, everytime I try to enable the firewall (by using ufw enable, for example), the system crashes silently.

I'm not saying that I lose the remote connection to the system, but that the system itself hangs, crashes. It doesn't respond to any key, even if I'm in the console.

I tried to search a little about this but I was unable to find anything regarding this issue.

Is anybody aware of this?

Thanks.
Regards.
