[squid-users] Problem with Squid 3.4 and transparent SSL proxy

[Job]

Hello,

i initialize correctly SSL Bump with Squid 3.4.4, following some guides.
In iptables i redirect 80 and 443 ports to squid ports.

Squid starts with no error, lines involving SSL bump are the following:

http_port 3128 intercept
https_port 3129 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=16MB cert=/etc/squid/ssl/squid.pem key=/etc/squid/ssl/squid.key

But no request arrives to squid.

If i telnet, from Linux machine, this:

telnet localhost 3128 or telnet localhost 3129, even though the socket is open (netstat -avn | grep 3128 and 3129), connection close immediately.

I see no errors in cache.log, access.log and messages.

Thank you
Francesco
