Hi I've recently set up a very simple Squid 3.3.1 deployment to test out Server First bumping and Mimicking in a REDIRECT type intercept configuration. It's working quite nicely, but I'm trying to accommodate a scenario where an admin would like to disable bumping for certain webistes, for example internet banking ones. I basically have the exact same "ssl_bump" parameters from the config example and yet requests matching the ACL are still being bumped as evidenced by: - The full HTTPS URLs being recorded in the access log. - My client browser continuing to show that the certificate is signed by the squid-signed CA when accessing the dstdomain. I feel like I'm making some obvious mistake here, but can't see the forest right now. In case it isn't clear in my config, I'm trying to prevent bumping the ACL "bump-bypass" Thanks! # # Recommended minimum configuration: # # Example rule allowing access from your local networks. # Adapt to list your (internal) IP networks from where browsing # should be allowed acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.0.0/12 # RFC1918 possible internal network acl localnet src 192.168.0.0/16 # RFC1918 possible internal network #acl localnet src fc00::/7 # RFC 4193 local private network range #acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT # # Recommended minimum Access Permission configuration: # # Only allow cachemgr access from localhost http_access allow localhost manager http_access deny manager # Deny requests to certain unsafe ports http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !SSL_ports # We strongly recommend the following be uncommented to protect innocent # web applications running on the proxy server who think the only # one who can access services on "localhost" is a local user #http_access deny to_localhost # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # # Let user specify domains to avoid decrypting, such as internet banking acl bump-bypass dstdomain .commbank.com.au # Example rule allowing access from your local networks. # Adapt localnet in the ACL section to list your (internal) IP networks # from where browsing should be allowed http_access allow localnet http_access allow localhost # And finally deny all other access to this proxy http_access deny all # SSL Settings # ssl_bump none localhost ssl_bump none bump-bypass ssl_bump server-first all sslproxy_cert_error deny all # Setup Options for the dynamic certificate db and helper sslcrtd_program /usr/bin/squid_ssl_crtd -s /usr/local//squid/var/ssl_db -M 4MB sslcrtd_children 5 # Listening ports http_port 3128 http_port 3129 intercept https_port 3130 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=/usr/local/squid/var/ssl_cert/myCA.pem # Leave coredumps in the first cache dir coredump_dir /var/spool/squid # Add any of your own refresh_pattern entries above these. refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 # DNS stuff visible_hostname squid.local # Making the access log have all the info we need strip_query_terms off # Debugging #debug_options 28,3 Access log excerpt: 1362457811.732 136 10.0.1.164 TCP_MISS/302 611 GET https://www3.netbank.commbank.com.au/netbank/bankmain - PINNED/140.168.80.158 text/html 1362457812.162 107 10.0.1.164 TCP_MISS/200 7673 GET https://www.my.commbank.com.au/netbank/Logon/Logon.aspx - PINNED/140.168.131.21 text/html 1362457812.695 75 10.0.1.164 TCP_MISS/200 7657 GET https://www.my.commbank.com.au/netbank/Logon/Logon.aspx - PINNED/140.168.131.21 text/html
