i have to configure my server to redirect from 80 and 443 port due to 8443 using iptables
-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 8443 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 443 -j ACCEPT
-A PREROUTING -i eth0 -p tcp -m tcp --dport 80:443 -j REDIRECT --to-ports 8443
when i browse like https protocol everything is working, but when from http, i can just donwnload a file, and don't see anything
8443
port is intended mainly to use as HTTPS proxy. Sending plain HTTP to this port will not work. You should keep separated HTTP and HTTPS traffic by sending them to a different port (normally 8080) of your transparent proxy.
using this rule : -A PREROUTING -i eth0 -p tcp -m tcp --dport 80:443 -j REDIRECT --to-ports 8443
you allowed only incoming traffic to to be sent to port 8443, but still the outgoing traffic needs to be routed
