I have a domain .club and when I run the tool nslookup the server does not respond, it responds only when I stop the service iptables and at that moment I can see my web page I have ports 80, 443, 10000, 3306 and 22.
INPUT DROP
ACCEPT TCP 80
ACCEPT TCP 443
ACCEPT TCP 10000
ACCEPT TCP 3306
ACCEPT TCP 22
FORWARD ACCEPT
OUTPUT ACCEPT
That would be for the moment the basic rules of iptables .
Thank you in advance for the help you can offer me
