I am trying to set a VPN server on my PC (Ubuntu). I am following a tutorial , http://cviorel.easyblog.ro/2009/02/09/how-to-set-up-a-vpn-server-on-ubuntu/.
I made changes in various files including /etc/ufw/before.rules file.
When I run command
sudo ufw disable && sudo ufw enable
Then I got following error message:
Firewall stopped and disabled on system startup
ERROR: problem running ufw-init
ufw version is 0.31.1-1
Can anyone please guide me! I don't have any prior experience...please can someone tell me the steps to fix this problem?
