Pretty much anything belonging with a frontend can be configured in the 'Advanced pass thru' field. Or did you mean something else? Something like this: http-response add-header Public-Key-Pins "pin-sha256=\"KEY1\"; pin-sha256=\"KEY2\"; max-age=15768000" p.s. Do start with low age like 60 seconds, until your sure you've got the configuration right.

Hi sherwinluissss, I configured pfsense 2.3.2 + squid (transparent with ssl inspection enabled)+ squidGuard. I have couple of issues skype is one of those. call are going fine but it is showing internet issue and not showing user as online it is keep trying to do get the status. can you please let me know how you solved your skype issue with squid. what are the hosts needs to be allowed i allowed skype.com live.com hotmail.com these three are using by skype atthe time of login. could you please help me how to fix this. My second problem is with multiple sip phones trying to connect one external pbx. no voice on incomming calls and no in and outbound voice ext to ext. Thanks in advance. Harry

so ok. i got it running. Reinstalled pfSense (this time i selected http) then restored the config (no problems with that) it works now, i can access on http thanks for the help

There is no such thing as a "kosher" certificate for SSL interception (unless you're the Chinese government, if rumors are to be believed). You must use a self-signed CA for SSL interception, and that CA must be installed on clients.

Ok, so we gonna have to deal with it. Thanks, David

Good catch.  Glad to hear t's now working as expected.

Just use squid + squidguard, but set squid's Hard Disk Cache Size to 0 and the Hard Disk Cache System to null.  This is exactly how I use squid.

Hi , I recently installed and played with this squid and squidGuard on pfsense 2.3.2 (updated with 2.3.2_1). I ran through the same issue. I mean when ever I enabled squidGuard with common ACL CN in certificate issued by  squid is "http" which doesn't make any sense to me. I thought the problem is with patch So I installed pfsense 2.3.2 again and tried it worked fine. But the reason is not patch. I enabled "Do not allow IP-Addresses in URL" this is causing the issue in my case. I just disabled this and tried it is working fine but when ever i try enable this running into issues. But it should be fixed  if it is a real bug. If this works for anyone please let me know I will create this in pfsense bugs list. Thanks, Harry.

I just got the squid and squidguard working as it was before (fingers crossed as I still need to do some test) but again, I couldn't have done it without your help will keep the configuration backup suggestion in mind for next upgrade and I'll get a tab screen capture to redo the config which is not that bad. Thank you again! Cheers!

HAProxy, hands down.

You need a program to look into the traffic - one possible solution is ICAP server - see https://docs.diladele.com/tutorials/filtering_https_traffic_squid_pfsense/index.html

LDAP/RADIUS should work with 0.4.26. NT Domain auth is gone with 0.4.29.
