UFW will save the rules so that they're still set after rebooting.
How can i block DOS and such things is there any guides to read about it ?
As far as I know, UFW isn't flexible enough to set up complicated anti-DDoS rules - you'll have better luck finding resources for iptables.
Okay thanks again :)
To protect against DDoS and other malicious attacks you'll want something like fail2ban:
