IPTables Ignoring Rule To Redirect Web Traffic

I am trying to do something very simple. I am trying to force all web request to go to my local webserver. I start by activating said webserver on my Kali Linux VirtualBox machine



sudo systemctl start apache2


Then I redirect all web traffic with iptables



sudo iptables -t nat -A PREROUTING -p tcp --dport 443 -j DNAT --to-destination 127.0.0.1:80

sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 127.0.0.1:80


Check to make sure the changes took effect



sudo iptables -t nat -L


They did



Chain PREROUTING (policy ACCEPT)
target prot opt source destination
DNAT tcp -- anywhere anywhere tcp dpt:https to:127.0.0.1:80


Now when I go to google.com or even example.com I just go to google.com as I normally would. How can I make the changes actually take effect?

          When you go to google.com, your packet never visit PREROUTING chain.
          Use OUTPUT instead.enter image description here

          • I tried your suggestion. sudo iptables -t nat -A OUTPUT -p tcp --dport 443 -j DNAT --to-destination 127.0.0.1:80 sudo iptables -t nat -A OUTPUT -p tcp --dport 80 -j DNAT --to-destination 127.0.0.1:80 . But after doing sudo iptables -L it looks like the output command is not being added. What did I do wrong?
