List Firewall Rules in RHEL

To list the firewall rules in Red Hat Enterprise Linux (RHEL), you can use the firewall-cmd command, like this:

sudo firewall-cmd --list-all

This will display a list of all the current firewall rules, including rules for incoming and outgoing traffic and rules for specific services or ports.

In addition to these commands, you can also use the iptables command to list the firewall rules in RHEL. Iptables is a utility that allows you to configure the Linux kernel’s built-in firewall. To list the firewall rules with iptables, you can use the following command:

sudo iptables -L

This will display a list of the current firewall rules, including the chain (INPUT, FORWARD, or OUTPUT) and the target (ACCEPT, DROP, or REJECT) for each rule.

Overall, there are several different ways to list the firewall rules in RHEL, depending on which tools you prefer to use. Whether you use service, firewall-cmd, or iptables, the process is relatively straightforward and can be helpful for troubleshooting network issues or for security purposes.
