RE: Squid HEAD : intercept SSLBump server first + out of Squid box NAT redirection

Hi,

Thank you for your answer.

I understand I cannot redirect SSL web traffic to intercepting Squid using NAT from another box, as Squid won't be able to figure out the destination address, right ?

Using the destination address of the intercepted TCP connection, Squid securely connects to the origin server, receives the origin server SSL certificate, and generates a fake SSL certificate by mimicking origin server certificate properties. After all of the above, Squid secures the connection with the client by performing an SSL handshake using the fake SSL certificate.
