      Good afternoon all,

      After upgrade to 2.7.1 squid service does not start. Below the error using squid -z command line. Can you help me please? I tried to restart service, cancel and reinstall package but nothing to fix it. Is referred to SSL and TLS option but I do not understand where I eventually have to modify options.

        I also found this problem after upgrade to 2.7.1
        It turns out that the regular expression has been changed after the squid package updates

        As you can see in this error log:

        2023/11/24 15:58:32| ERROR: configuration failure: POSIX regcomp(3) failure: (13) repetition-operator operand invalid
regular expression: .google.com/

2023/11/24 15:58:32| Squid Cache (Version 6.3): Terminated abnormally.

        It turns out that .google.com/ in ACL Whitelist is no longer the valid regular expression
        It should be changed to \.google.com/ (I'm not sure if my regex is correct, but it's enough for squid to continue function)

        EDIT: Oops, looks like your problem was in ACL Whitelist. For me, it was Custom refresh_patterns

          No way wynn1212. Squid has been deprecated for Security reason. Too much Vulnerability not corrected are present. For this reason this Packet will be deprecated and not included in q the next release. RIP Squid in PFSense

            Hello everyone. When squid proxy is removed from pfsense in new version, what is the alternative? I use squid for outboind proxy with multple IPs?

                  Hi, I couldn't solve it.

                  I'm looking for an alternative solution but I can't find anything at the moment

                  Greetings

                    @JonathanLee If I remember correctly, those 2 error are not FATAL, and should not preventing squid to start. unless you really need this feature.
                    If squid failed to start, please check FATAL message instead of ERROR message.

                      Does anyone know how to activate the TLS1.3 ciphers? This might fix some issues....
                      Per lists.squid-cache.org

                      Ref:
                      https://openssl.org/blog/blog/2017/05/04/tlsv1.3/
                      https://lists.squid-cache.org/pipermail/squid-users/2018-February/017640.html

                      And CVE-2016-0701

                      "Yes. Due to CVE-2016-0701 the SSL_OP_SINGLE_DH_USE option was deprecated”

                      It is depreciated and the new pfSense package still shows it as a default option, however how does one append

                        Try to modify /usr/local/pkg/squid.inc
                        from

                        $sslproxy_options .= ",SINGLE_DH_USE,SINGLE_ECDH_USE";
to 
//$sslproxy_options .= ",SINGLE_DH_USE,SINGLE_ECDH_USE";

                        Check configuration with the command

                        squid -k parse

                        tls_outgoing_options cipher=EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH+aRSA+RC4:EECDH:EDH+aRSA:HIGH:!RC4:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS
