i think they can’t run both(iptables and ufw)
maybe you can find some help here: Firewalls - Manjaro
As @linub has previously mentioned.
It is worth noting that while ufw uses iptables to do its job, you should not enable
its service while using ufw.
While using the ufw service, do not enable iptables.service
Are you sure? Can you check status with the following command:
sudo ufw status verbose
Also, please see: [SOLVED] every boot ufw status inactive - Applications - Manjaro Linux Forum
how check if extras installed?
[sudo] heslo pro adam:
Logging: on (low)
Default: deny (incoming), allow (outgoing), disabled (routed)
New profiles: skip
i tryed disable iptables.service but ufw write error with ip6tables
To disable iptables:
systemctl disable iptables.service
It looks like ip6tables .service is preset to disabled on my system. In fact I have ipv6 disabled entirely on my system through a kernel parameter. It appears that your firewall is active and running from the output listed above.
All ufw extras is, is some preset rules that get applied when you install it. Setting rules in GUFW is easy. That is the whole point of the GUI for the firewall. So, you probably do not need “extras”.
UFW Extras are additional rules to easily configure some services, this has nothing to do with the issue here.
