How To Open http Port 80 On Redhat 7 Linux Using firewall-cmd
Article By: tapish01 Ranjan
In this tutorial you will learn how to open port 80 on Redhat 7. By default, port 80 for the http connection is filtered on Redhat 7. You can only access this port from the actual localhost and not from any other public host. To open port 80 on RHEL 7 Linux we need to add an iptables rule. For this RHEL7 uses firewall-cmd. |

First add your port 80 rule with a following command:
[root@bip1987 ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent
Once you add the above rule reload the service:
[root@bip1987 ~]# firewall-cmd --reload
And check whether the port was added to ipatables rules:
[root@bip1987 ~]# iptables-save | grep 80 -A IN_public_allow -p tcp -m tcp --dport 80 -m conntrack --ctstate NEW -j ACCEPT
If you decide to block/remove the http port 80 rule you can again and use the cmd command:
[root@bip1987 ~]# iptables-save | grep 80 -A IN_public_allow -p tcp -m tcp --dport 80 -m conntrack --ctstate NEW -j ACCEPT [root@bip1987 ~]# firewall-cmd --zone=public --remove-port=80/tcp --permanent success [root@bip1987 ~]# firewall-cmd --reload success [root@bip1987 ~]# iptables-save | grep 80 [root@bip1987 ~]#
