best way to configure a firewall on RHEL7
hi guys,
read this: The RHCSA objective does not define which tool you should use to create firewall rules. It just mentions that you should be able to create firewall rules by using iptables, firewall-config, or firewall-cmd. So, you do not have to be able to work with each of these tools; you just have to be able to configure a firewall with the tool that works best for you. what would you recommend and why? iptables firewall-config firewall-cmd thanks |
Hi,
My recommendation is firewall-cmd. iptables is still good, but it is the past. |

so tbone,
it doesnt really matter? they all accomplish the same thing but isnt there pros and cons to doing thins differently? the previous poster said iptables is in the past...do you agree? |
I believe all three options use iptables. The other two simply parse iptables rules. Once I started using iptables directly it was so much easier to lock down a network exactly the way I wanted that I just kept using it.

use bash

Redhat does everything to try and stand out even to the point of trying to make the way they do things the standard. Since you are taking the test you need to decide what works best for you and what you can use to complete the task at hand in a timely matter as in the end that is what counts, complete each task correctly in a timely matter. |
