I know it can be done in iptables, however I would like to use the firewalld service.

Red Hat Active Contributor 218 points 4 May 2017 8:26 PM Albert Wong Just to add a side question.... Can you add the ip or range to the "blocked" or "drop" firewalld zone? No because interfaces are not active on those zones. Active Contributor 202 points 26 May 2017 1:13 PM Chris Scarff Great info, thanks for sharing! Newbie 5 points 28 September 2017 8:48 PM V R I just added the following to the drop zone and it worked without any issue: firewall-cmd --zone=drop --add-source=x.x.x.x/xx replace x.x.x.x with the IP and you can add the subnet under /xx Was this helpful?
