Hello,
I've noticed that after a fresh install I have few filtering rules that
I do not need and would like to get rid of:
[root@localhost ~]# iptables -n -L -v

[root@localhost ~]#
I failed to find anything that adds these rules. Is it hardcoded? If
not, how do I disable them without writing a script to flush iptables?
Hi,
i guess rules are created upon firewalld configuration.

may be just disable firewalld service.
