Iptables problem


#1

Hi,
I have tried to block all ips except the cloudflare server ips. I tried with iptables:

-iptables -P INPUT DROP

-iptables -I INPUT -p tcp -m multiport --dports http,https -s 103.21.244.0/22 -j ACCEPT
-iptables -I INPUT -p tcp -m multiport --dports http,https -s 103.22.200.0/22 -j ACCEPT

-ip6tables -I INPUT -p tcp -m multiport --dports http,https -s 2a06:98c0::/29 -j ACCEPT

-iptables-save > /etc/iptables/rules.v4
-ip6tables-save > /etc/iptables/rules.v6

but unfortunately that caused that my site is not more accessible :frowning:

I used that IP list:

I hope someone can help me :slight_smile:
