Firewalld runs as a background process, allowing dynamic modification of packet filter rules via D-Bus, without the need to reload the filter rules and without interrupting established connections. The project is already being used in many Linux distributions, including RHEL 7+, Fedora 18+, and SUSE\/openSUSE 15+. The firewalld code is written in Python and is distributed under the GPLv2 license.      <\/p>\n<p>The firewall is managed using the utility firewall-cmd, which creates rules based not on <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/lir\/ipv4\/\"   title=\"(the key to connect to is specified, and iroh finds the associated host and establishes an encrypted connection using the QUIC protocol).
