どのように動作させることができますか？firewalld手順は次のとおりです。
sudo firewall-cmd --zone=public --permanent --add-service=postgresql
sudo firewall-cmd --zone=public --permanent --add-port 5432/tcp
sudo firewall-cmd --permanent --add-source=192.168.1.24
sudo firewall-cmd --permanent --add-user1-rule='rule family="ipv4" source address="192.168.1.24" port protocol="tcp" port="5432" accept'
sudo firewall-cmd --reload
sudo firewall-cmd --list-all
