I come from iptables (didn't know it well but enough to get
by). I am trying to learn firewalld now which appears to be much more powerful.
First of all I need some help, please.
I would like to remove all the rules and zones since I have probably messed up my
installation so far and do the following:
You can remove the user configuration files in the directories
`/etc/firewalld/*/`. Do firewalld.conf or lockdown-whitelist.xml files.
I would like to "DROP" all outside traffic I would thenÂ
like to only allow all ports from (2) two IP addresses.
Could someone explain to me how to do this.
1. Make "block" or "reject" the default zone.
# firewall-cmd --set-default-zone=block
2. Then add your allowlist IPs to the trusted zone which allows
everything.
# firewall-cmd --permanent --zone trusted --add-source <ip_address>
# firewall-cmd --reload
My configuration only has:
(1) one public IP Address (ens3)
Thanks in advance.
Also, is there a good tutorial that would walk me through learning firewalld? Thanks
again for this as well.
Have a great day.
The upstream website has some documentation:
