Port forwarding isn't the answer.
What have you done to enable the SSL proxying in the Squid
Why are you trying to proxy HTTPS? If you're trying to cache it, you're
violating security, and I don't think it's going to let you do that.
Secure web browsing really needs *NO* man in the middle.
But if you're tunnelling SSL through Squid (uncached proxying), that's a
different matter (still a security risk to those wanting to use secure
websites through your proxy, not always done, but technically feasible).
The last time I set up Squid, was with FC4, so it's an older version,
and options may have changed since then. But you have to go through the
ACL rules, list the ports used for SSL, and add them to the safe ports
rule. And allow the safe and SSL ports through the access rules.
Snippets from my configuration:
acl SSL_ports port 443 563
acl Safe_ports port 443 563 # https, snews
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
Don't confuse yourself with the SSL accelerator configuration, that's
for using Squid to aid your own secure webserver, if you have one.
Have you looked at:
(This computer runs FC7, my others run FC4, FC5 & FC6, in case that's
important to the thread.)
