      @doktornotor:

      Apparently it wouldn't, because it's already there (twice - at the checkbox info and at the textarea info), but you still didn't read it.  :P (Try clicking the blue "i")

      Actually I did read them, but the descriptions didn't seem to be fully clear to me.  ???

      I do appreciate the updates however - they're working great.  8)

        Hi All, please can someone explain which settings on the GUI I should change to be able to do same SSLbump without MITM like the OP? I too don't want any certs on clients but want to block HTTPS sites.

            @Bismarck, I've tried this. There are still so many SSL cert errors on the workstations. Are there any other fine-tuning I could do?

              @kopraasbotha said in SSLBUMP without MITM:

              SSL cert errors

              There should none, what kind of SSL cert errors you get, example?

                  This looks like SslBump and not like SpliceAll, to me but I'm not a real Sqiud "Pro" tbh.

                  Do you have any custom config setup?

                  Please post the "# SslBump Peek and Splice" part of your /usr/local/etc/squid/squid.conf

                    @Bismarck i didn't add any custom config. Here's the "sslbump peek and splice" config:

                    acl step1 at_step SslBump1
                    acl step2 at_step SslBump2
                    acl step3 at_step SslBump3
                    acl allowed_subnets src 10.11.0.0/21 10.0.0.0/24
                    acl whitelist dstdom_regex -i "/var/squid/acl/whitelist.acl"
                    http_access allow manager localhost

                    http_access deny manager
                    http_access allow purge localhost
                    http_access deny purge
                    http_access deny !safeports
                    http_access deny CONNECT !sslports

                      Yep, your config is SslBump and not Splice, but dunno why. Maybe some more expert can chime in.

                        @Bismarck ,thanks for the help. I saw the ssl_bumps just underneath "custom options before auth" but there's a 2 line space between this section and the config so not sure if it's part of it.

                        Custom options before auth

                        acl sglog url_regex -i sgr=ACCESSDENIED
                        http_access deny sglog
                        ssl_bump peek step1
                        ssl_bump splice all
