Firewalld
Another package to manage another package… welcome to new world … :D
Anyway but server need to keep rolling !!
Replace firewalld with iptables
This is tested with the RHEL7
yum install -y iptables-services iptables-save > /etc/sysconfig/iptables # preserve existing rule systemctl stop firewalld systemctl mask firewalld systemctl enable iptables systemctl enable ip6tables systemctl start iptables systemctl start ip6tables
Adding rich rule
firewall-cmd --permanent --zone=public --add-rich-rule=' rule family="ipv4" source address="192.168.12.0/25" port protocol="tcp" port="9200" accept'
Port redirection
Using following command one can redirect port traffic to another.
# iptables -t nat -A PREROUTING -i eth2 -p tcp --dport 8080 -j REDIRECT --to-port 8443 firewall-cmd --permanent --direct --add-rule ipv4 nat OUTPUT 0 -p tcp -o lo --dport 8080 -j REDIRECT --to-ports 8443
