That is the best type to have when you can. Because it lets you use the full capabilities of proxying in HTTP. However, it also means that the clients do not use DNS nor /etc/hosts file. The proxy is what does DNS lookups about where to send the traffic the client(s) ask it to fetch. > but when i try to using /etc/hosts i cannot access to https websites. HTTPS is designed to prevent people playing around with the traffic.

That means you do not own the secret encryption key that HTTPS associates with that domain name. That means you cannot setup your proxy to perform encryption/decryption of traffic when acting as a web server for it. The only options you have for HTTPS are: 1) to use the proxy as a proper forward/explicit proxy the normal way HTTP does that. Or 2) to forget the idea of setting your own IP as web server and use MITM interception of the clients normal port 443 traffic with SSL-Bump feature enabled in your Squid. > > *My Iptables config is:* > > iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 3130 > That is okay. It is the (2) option mentioned above. Be aware that it is incompatible with the idea of setting /etc/hosts IP address for the domain as a way to get it to the proxy. This iptables rules is the way to catch client traffic already on its way to the *real* domain server(s) and send it through the proxy instead. It is a bit nasty to work with, but still way better than MITM through /etc/hosts entries. > *My squid config is:* > <snip> > > http_port 3128 Okay.

You need to see the errors to even start to find solutions.
