Hi. I finally did squid 3.3.10 ssl-bump works. I test on different site that use https and works, but after testing and surfing normally, I start having issue example with ebay. I try to purchase something and once I try to pay I receive this error in my browser, firefox: The following error was encountered while trying to retrieve the URL: ://checkout.payments.ebay.com:443 Failed to establish a secure connection to site-ip The system returned: (92) Protocol error (TLS code: X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY) SSL Certficate error: certificate issuer (CA) not known: /C=US/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=Terms of use at https://www.verisign.com/rpa (c)10/CN=VeriSign Class 3 Secure Server CA - G3 This proxy and the remote host failed to negotiate a mutually acceptable security settings for handling your request. It is possible that the remote host does not support secure connections, or the proxy is not satisfied with the host security credentials. This error appear to with chrome. Other issue, I have 2 banks accounts, in 1 bank no problem, I could access my account, with other I could not, the issue there is that I didn't receive a error like the one I show u, the error was some popups windows that give some info about my IP, but those are messages from the app the bank use. But once I disable ssl-bump everything back to normal with this bank. I create my ca using pfsense tools. What is the issue with this error and how we could fix it, exits a way to troubleshoot this? pfsense2.1, squid3.3.10, x64, thanks.
