Nach Stunden des Kämpfens mit #firewalld: immer wieder "administratively filtered". Also alles gelöscht und den Weg von #iptables gewählt – und trotzdem, nix läuft. Kein #Internet, nur Frust.

Verliere langsam, aber sicher, die *Verbidung* mit der Realität.

Hab mehr *Pakete* verloren als FedEx.

Is there a #FreeBSD 1[34]] #pf to #RockyLinux 8 #iptables, #firewalld <https://docs.rockylinux.org/guides/security/firewalld-beginners/>, or whatever else converter?

I will take a table that would guide how to manually convert the syntax of pf.conf(5) <https://man.freebsd.org/cgi/man.cgi?query=pf.conf&apropos=0&sektion=5&manpath=FreeBSD+14.1-STABLE&arch=default&format=html>.

My search skill is nowhere today. Does anyone have a good means of sharing blocklists for #firewalld or sending #fail2ban events to multiple servers?

Do you know how to set up a secure firewall for your network? Our 'firewalld' tutorial has had good reviews from users. It can walk a beginner through the process of setting up the default Rocky Linux firewall daemon. For users with some previous knowledge of older firewall technologies, the IpTables Guide helps translate that knowledge into the 'firewalld' setup. https://docs.rockylinux.org/guides/security/firewalld-beginners/ #tutorialtuesday #firewalld #howto #linuxtips #documentation

How to Install #Firewalld on #Debian 12/11/10

PSA: if you run #Fedora 36 or later, check to see if your #firewalld service is running.

In a recent update they're still distributing a broken tcpcryptd.xml service definition file for which this over 4 year-old bug exists even though there are merge requests for fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1716080

What's really awful is it causes firewalld to not start and you won't notice unless you monitor its state. Ouch.
