Thank you, I have put my firewall rules into /etc/sysconfig/iptables:
*filter
:INPUT DROP [0:0]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [294:35064]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p icmp -m icmp --icmp-type any -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp -m multiport --dports
25,80,443,8080 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 --tcp-flags
FIN,SYN,RST,ACK SYN -m limit --limit 2/min --limit-burst 1 -j ACCEPT
COMMIT
Then issued the commands (there was no firewalld installed):
# yum install iptables-services
# systemctl enable iptables
# systemctl start iptables
And it seems to work well now
Regards
Alex
