I am using Squid proxy 3.1, all systems in the LAN connects to the internet through proxy. Direct connection is blocked using the iptables from the gateway server.
There are some devices which does not have options for auto proxy or manual proxy and can only connect to the internet directly. So I enabled transparent proxy in Squid and redirected packets for port 80 and 443 to Squid proxy using iptables.
Now the problem is it is working fine for HTTP port but HTTPS is not working. It is throwing "ssl_error_rx_record_too_long" error.
If it is not possible through transparent proxy can you please suggest me another solution.
