Where does UFW (uncomplicated firewall) save command-line rules to?

  • 772

You add a rule like this:

ufw allow 22/tcp

The rule is saved, and is applied even after reboot. But it's not written anywhere in /etc/ufw. Where is it saved to? (Ubuntu, using ufw as pre-installed.)

iptables

    In my Ubuntu 11 server, the firewall rules are saved in /lib/ufw/user.rules

  2. Ubuntu 16.04 LTS

    /etc/ufw/user.rules

    Debian 9

    /etc/ufw/user.rules

    In general, try:

    locate user.rules

    Should output something like:

    /etc/ufw/user.rules
/usr/share/ufw/user.rules
/usr/share/ufw/user.rules.md5sum
/usr/share/ufw/iptables/user.rules

  3. I believe it's under lib/ufw/rules[6].rules

  4. In my version, 8.04 LTS Server the files are stored in /var/lib/ufw as /var/lib/ufw/user.rules and /var/lib/ufw/user6.rules.

  5. This should work on all Linux systems assuming a ".rules" suffix and residing beneath a directory named "ufw":

    sudo find / -name "*.rules" -exec ls -l {} \; | grep ufw

    Using the "ls -l" shows that some of them are links to others, and which ones have been updated most recently (implying they are active?)
