Why does my IPTables changes not deny access from all IP addresses except CloudFlare’s ranges?

General

I am running apache on ubuntu 18.04. I used IPtables to deny access from all IP addressed except CloudFlare’s ranges and when I run iptables -L –line-number I get

1 ACCEPT tcp – 131.0.72.0/22 anywhere multiport dports http,https
2 ACCEPT tcp – 172.64.0.0/13 anywhere multiport dports http,https
3 ACCEPT tcp – 104.16.0.0/12 anywhere multiport dports http,https
4 ACCEPT tcp – 162.158.0.0/15 anywhere multiport dports http,https
5 ACCEPT tcp – 198.41.128.0/17 anywhere multiport dports http,https
6 ACCEPT tcp – 197.234.240.0/22 anywhere multiport dports http,https
7 ACCEPT tcp – 188.114.96.0/20 anywhere multiport dports http,https
8 ACCEPT tcp – 190.93.240.0/20 anywhere multiport dports http,https
9 ACCEPT tcp – 108.162.192.0/18 anywhere multiport dports http,https
10 ACCEPT tcp – 141.101.64.0/18 anywhere multiport dports http,https
11 ACCEPT tcp – 103.31.4.0/22 anywhere multiport dports http,https
12 ACCEPT tcp – 103.22.200.0/22 anywhere multiport dports http,https
13 ACCEPT tcp – 103.21.244.0/22 anywhere multiport dports http,https
14 ACCEPT tcp – 173.245.48.0/20 anywhere multiport dports http,https
15 ufw-before-logging-input all – anywhere anywhere
16 ufw-before-input all – anywhere anywhere
17 ufw-after-input all – anywhere anywhere
18 ufw-after-logging-input all – anywhere anywhere
19 ufw-reject-input all – anywhere anywhere
20 ufw-track-input all – anywhere anywhere
21 DROP tcp – anywhere anywhere multiport dports http,https

The exact command I ran was:

sudo iptables -I INPUT -p tcp -m multiport --dports http,https -s 173.245.48.0/20 -j ACCEPT 
sudo iptables -I INPUT -p tcp -m multiport --dports http,https -s 103.21.244.0/22 -j ACCEPT 
sudo iptables -I INPUT -p tcp -m multiport --dports http,https -s 103.22.200.0/22 -j ACCEPT

sudo iptables -I INPUT -p tcp -m multiport --dports http,https -s 188.114.96.0/20 -j ACCEPT 
sudo iptables -I INPUT -p tcp -m multiport --dports http,https -s 197.234.240.0/22 -j ACCEPT 
sudo iptables -I INPUT -p tcp -m multiport --dports http,https -s 198.41.128.0/17 -j ACCEPT 
sudo iptables -I INPUT -p tcp -m multiport --dports http,https -s 162.158.0.0/15 -j ACCEPT 
sudo iptables -I INPUT -p tcp -m multiport --dports http,https -s 104.16.0.0/12 -j ACCEPT 
sudo iptables -I INPUT -p tcp -m multiport --dports http,https -s 172.64.0.0/13 -j ACCEPT 
sudo iptables -I INPUT -p tcp -m multiport --dports http,https -s 131.0.72.0/22 -j ACCEPT 


sudo iptables -A INPUT -p tcp -m multiport --dports http,https -j DROP

Why am I still able to access the website from direct Digitalocean droplet IP address? Thanks

@sdayman I already did this and when I run iptables -L --line-number I get

Why am I still able to access the website from direct ip?

I am afraid that is a server administration related question and somewhat off topic for the forum here. Please try over at StackExchange.
