It seams that haproxy does not include the hostname in the path. I've changed my hcl like this: path starts with /MySite host equals www.mysite.com This works perfectly. Thanks for your help.

Those config options you mention are for squid.. Maybe however you could try adding 'option prefer-last-server' in the the advanced section of the backend. http://cbonte.github.io/haproxy-dconv/snapshot/configuration-1.6.html#4.2-option%20prefer-last-server Haproxy does not strip headers away unless it is configured to do so.. Could you perhaps post the haproxy.cfg to see if there are any options mentioned that might interfere? And give a little more understanding about your setup. p.s. The client browsers do have sharepoint.company.url configured in their 'local intranet' settings in IE ? AFAIK for 'internet' and 'trusted websites' the NTLM authentication is never automatically send. But i could be wrong there..

Fair enough. It's been a while since I've looked at this particular combination (Squid/AD) so I guess I fell out of the loop a bit.

I found this: https://github.com/pfsense/FreeBSD-ports/pull/34 Any idea when this will come into squid? This is needed for reverse proxy but the question is will there be a auth delegation to the proxy for sharepoint and owa?

OK, get rid of that and install the squid3 package.  That's your problem.  That package is for squid2 which is ancient and I'm not even sure it works properly.  Your eperiences seem to confirm that something weird is going on.  The squid3 package is the only one really being maintained moving forward, so you should use that one.

This should work.. Have you tried inspecting (tcpdump/wireshark) the traffic between haproxy and backend? And haproxy itself does perform ssl offloading right?

@phoenixsampras: Same Problem!! Dear lord, is pfsense getting worst with every version?? now https doesnt work with proxy….. traffic shapping doesnt work with XENSERVER, etc. What's wrong Pfsense?? this are basic stuff!! come on!! yeah  ::)

Some more info… The proxy seems to work fine (normal and transparent) if I set the proxy settings in my browser.  However, if I have transparent proxy enabled and remove the proxy settings from my browser, that's when I can't browse any more. It seems like the requests just aren't being routed properly.  How is the routing through the transparent proxy done?

Any update on this squiguard cannot be install on a new version of pfsense.

If I remember, you have to add the IP address that squid listens on to the External cache Managers field in Services - Squid Proxy Server - Local cache.  Your output should look like this: [2.2.5-RELEASE][admin@pfsense.kominc.local]/root: squidclient -h 10.10.4.1 -p 3128 mgr:info Sending HTTP request ... done.

In the backend edit page: Transparent ClientIP WARNING Activating this option will load rules in IPFW and might interfere with CaptivePortal and possibly other services due to the way server return traffic must be 'captured' with a automatically created fwd rule. This also breaks directly accessing the (web)server on the ports configured above. Also a automatic sloppy pf rule is made to allow HAProxy to server traffic. Maybe i should add that accessing haproxy-ip from the same network as where the server exists will be an issue to.. When that box is checked. This problem is similar, method 2 should work with haproxy: https://doc.pfsense.org/index.php/Why_can't_I_access_forwarded_ports_on_my_WAN_IP_from_my_LAN/OPTx_networks But do check your not trading 1 problem for another again.. OPT1 clients might not like the splitdns accessing the server on LAN…

Only way to get a redirect when visiting a blocked https website is if you use MITM method instead of WPAD.  Basically Squid will break an HTTPS tunnel, but isn't able to tell the browser to redirect since you aren't trusting the proxy server to handle the connection.  You are just tunneling through it when using wpad.

@laren626: Everything works fine But there is a problem IDK why it is not serving as a proxy server I got this on my Squid Logs 05.02.2016 10:25:21 Starting Squid Cache version 3.4.10 for amd64-portbld-freebsd10.1… 05.02.2016 10:25:43 172.0.100.203 TAG_NONE_ABORTED/000 http://www.msn.com/ It may occur when you select loopback interface to listen squid on. Try to select only lan, restart the service and test again.

@osaka26: Enable DNS Resolver, Host Overrides; add; on host: www; Domain: google.com; ip address: 216.239.32.20; Save, then ipconfig /flushdns and voila google safesearch on all lan!  

any ideas on this? This is normal and the reason you should avoid transparent mode unless you plan on installing a pfSense certificate into every client that will use the proxy.

You don't want an open proxy, it'll probably be no more than a few hours until someone finds it and starts abusing it. Much better off setting up a VPN and routing all traffic through it.

I might suggest that you try going through a free short online Linux Basics tutorial before you go any further so that you get some needed education on how to move around the file system, how to create & copy files, etc, or this entire exercise will just frustrate you.  Here is one, for example: https://www.edx.org/course/introduction-linux-linuxfoundationx-lfs101x-2 Note that pfSense is based on FreeBSD, not Linux, but all the same concepts still apply. Creating these scripts by typing them in manually is a guaranteed way to make a mistake.  You are better off cutting & pasting the scripts into their respective files on your local computer and then using a pfSense package like File Manager to actually upload the script files to their destination on pfSense.  Then you can try to run them.

You could add a cron job to do it for you but you would be better off figuring out the real problem.  Anything in /var/squid/logs/cache.log?
