Dectivate firewalld Rules
Firewalls can be used to separate networks into different zones based on the level of trust the user has decided to place on the devices and traffic within that network. Firewalls can be implemented using variety of software tools and services, i.e. iptables, nftables, firewalld, ufw, SuSEFirewall2 etc. Having more than one service controlling the firewall functionality may lead to conflicts and misconfiguration. Therefore, in case one uses iptables or nftables firewalld service should be disabled.
