Created attachment 162218 [details] screenshot SUMMARY I hope this is the right product/component sine this is about the plasma-firewall package. When I open the KCM in the systemsettings it shows the value "IPv4" in the column "IP" for all service rules, even the IPv6 ones. The backend is firewalld. STEPS TO REPRODUCE 1. Enable firewalld, disable ufw 2. Open firewall in system settings 2. Type in your password (I am prompted three our four times for the password for whatever reason) 3. Look at the list of incoming rules OBSERVED RESULT The column "IP" says "IPv4" for all rules defined by services even those which are obviously IPv6 (like dhcpv6-client) EXPECTED RESULT It should say "IPv6" SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon User Edition (available in About System) KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.110.0 Qt Version: 5.15.10 firewalld version: 1.1.1 ADDITIONAL INFORMATION
I found the issue. It's in line 484 of kcm/backends/firewalld/firewalldclient.cpp. It says false where it should have said true. Permalink: https://invent.kde.org/plasma/plasma-firewall/-/blob/d91ae458d938d0c8fb12e17232e3d22f575b0e31/kcm/backends/firewalld/firewalldclient.cpp#L484 However, even if you fix that, it's not really a solution. For example, if you look at the dhcpv6-client service which you gave as an example, it's an IPv6 rule only. Command to see: firewall-cmd --permanent --info-service=dhcpv6-client The code I linked above creates an IPv4 and an IPv6 line regardless of what the service actually uses.
