Hi, my centos 7 server is using iptables so I cannot use the firewall-cmd commands to open the email ports as shown in this post.
The idea is to replace iptables with firewalld, but I understand that they can't be used both simultaneously. Any guide or advice on how to properly migrate from iptables to firewalld will be much appreciated, thanks. |
