      hi i have instaled pfsense v2.1.4 i386 with this packages:
      squid3-dev v3.3.10 pkg 2.2.6, working SSL man in the middle for filtering HTTPS
      snort 2.9.6.2 pkg v3.1.1
      pfblocker 1.0.2

      All working well (included eicar test http://www.eicar.org/85-0-Download.html  file scaning with c-icap) without instaled diladele ( http://docs.diladele.com/administrator_guide_3_4/installation_and_removal/install_on_freebsd.html).

      When i instal Diladele  ( http://docs.diladele.com/administrator_guide_3_4/installation_and_removal/install_on_freebsd.html and add 'always_direct allow all; ssl_bump server-first all' to squid config), then i can filter https, http but scaning downloaded file (for examle exe, zip, com, txt) with virus scanner not working.

      Can you pleas link me to some solution?

      Thx,

      Marian L.

      pfsense runing in virtual, on HP N54L microserver, 2G RAM, 60G disk, WAN, LAN, DMZ, Wifi, OpenVPN server + client, suricata, pfblocker

        ok, today i make some research and find how to chaining diladele and c-icap for filtering https and scaning downloaded files. I change /usr/pbi/squid-i386/etc/squid/squid.conf (problem is, i dont for now, how to make changes permanent:

        chanched in squid.conf (also changet listening port in antivirus settings in pfsense UI to 1345):

        and some settings in clamd.conf (enable archive scanning and executable). I dont know if this help for scaning files, but i made it….

        # Uncomment this option to enable logging.
        # LogFile must be writable for the user running daemon.

        # in bytes just don't use modifiers. If LogFileMaxSize is enabled, log

          huh, reply to myself  :P …..

          ok, permanent changes can make via pfsense UI.

          1. set listening port "Antivirus" in "c-icap.conf" to "Port 1345"

          2. set this in Custom ACLS (Before_Auth), with help of Diladele support:

          
          always_direct allow all
          ssl_bump server-first all
          icap_enable on
          icap_preview_enable on
          icap_preview_size 4096
          icap_persistent_connections on
          icap_send_client_ip on
          icap_send_client_username on
          icap_client_username_header X-Client-Username
          
          icap_service qlproxy1 reqmod_precache routing=0 bypass=0 icap://127.0.0.1:1344/reqmod
          icap_service qlproxy2 respmod_precache routing=0 bypass=0 icap://127.0.0.1:1344/respmod
          
          icap_service service_req reqmod_precache routing=0 bypass=0 icap://127.0.0.1:1345/squidclamav
          icap_service service_resp respmod_precache routing=0 bypass=0 icap://127.0.0.1:1345/squidclamav
          
          acl qlproxy_icap_edomains dstdomain "/opt/qlproxy/etc/squid/icap_exclusions_domains.conf"
          acl qlproxy_icap_etypes rep_mime_type "/opt/qlproxy/etc/squid/icap_exclusions_contenttypes.conf"
          
          adaptation_service_chain chain1 qlproxy1 service_req
          adaptation_access chain1 deny qlproxy_icap_edomains
          adaptation_access chain1 allow all
          
          adaptation_service_chain chain2 qlproxy2 service_resp
          adaptation_access chain2 deny qlproxy_icap_edomains
          adaptation_access chain2 deny qlproxy_icap_etypes
          
          adaptation_access chain2 allow all
          
          

          but after save and restart squid service, in squid.conf remain this on end of file (always, because is autogenerated and i dont know where is template for generatin to delete these lines):

          
          icap_enable on
          icap_send_client_ip on
          icap_send_client_username on 
          icap_client_username_encode off
          icap_client_username_header X-Authenticated-User
          icap_preview_enable on
          icap_preview_size 1024
          
          icap_service service_req reqmod_precache bypass=0 icap://127.0.0.1:1344/squidclamav
          icap_service service_resp respmod_precache bypass=0 icap://127.0.0.1:1344/squidclamav
          
          adaptation_access service_req allow all
          adaptation_access service_resp allow all
          
          

          Can you pleas verify my settings and tune it? Thx.
