HTTPS Filtering + Splice All gives certificate issues

Stewart

I thought doing a splice all would negate having certificate issues. We are looking to do domain filtering through squidguard to keep people out of places they shouldn't go. Doing just HTTP seems to work fine. Doing HTTPS has been far more problematic. I understand that if I want to scan HTTPS for infections and content then I need to Bump which requires certificates. If I just want to use SquidGuard to stop people from going to places like Netflix then I just need to splice all. I have a couple of problems and I'm not sure what they are. All tests are done on fresh installs of Windows 7 with IE 11. I've also reset pfSense to factory defaults and the only configuration is the WAN IP and adding in Squid and SquidGuard. SquidGuard is set to block gambling, movies, and porn and allow by default. Nothing else has been changed.

Problem 1:
On PC1 if I go to http://ww.google.com it automatically redirects me to https://www.google.com as I expect. On PC2 when I go to http://www.google.com it returns:
Request denied by pfSense proxy:403 Forbidden.
Client group: default
Target group: none
URL: http://www.google.com
On PC2 if I go to https://www.google.com it works just fine so it isn't being blocked.
I've tried clearing the cache of Squid and the browsers on each machine and it doesn't change.

Problem 2:
Even though Squid is set to Splice all, when I go to pages such as https://www.hulu.com it returns:
This page can't be displayed
Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://www.hulu.com again.

Some more things that may help:

The block log. HTTP traffic is set to REDIRECT while HTTPS traffic is set to CONNECT REDIRECT

I think what I'm trying to do is pretty basic. Has anyone gotten this working so that it's only Peek and Splice so no certificate is needed and SquidGuard can filter?

Stewart

An Update: I've tried both "Splice All" and a "Custom" set that I've found.


# peek at client TLS-request to get SNI
# peek at server cert (for logging)
# splice earlySplice at step 3 only
ssl_bump peek step1
ssl_bump peek step2 earlySplice
ssl_bump splice step3 earlySplice
ssl_bump splice all
sslproxy_cert_error deny all

but it gives the same issue.

EDIT: SCRATCH THAT. ONCE I RESTARTED SQUID IT WOULDN'T START AT ALL. I HAD TO REMOVE THIS CODE FOR IT TO FIRE UP AGAIN. IT GAVE ME AN ERROR ON LINE 130 WHICH WAS ssl_bump peek step2 earlySplice

I've also tried every combination I can make of the options in Remote Cert Checks and Certificate Adapt.

Disabling squidGuard seems to work better so that's likely the reason for the SSL errors. Maybe the error page? On some PCs loading Hulu and Netflix just sit there spinning. On others they load right up. I just don't know why there is such inconsistency across the network. This is a test environment with just a few PCs and a server so nothing fancy and nothing that another wipe would hurt too much.

Also you can set up your own DNS servers for Squid in Squid settings - should match what's used on clients. (It doesn't need to use the ones set up in pfSense.)

@Stewart did you ever get a final config you were satisfied with.
I wanted the benefit of both caching and filtering and had browsing work (except for android) but my linux emails clients couldn't work.

All squid can do when it blocks a spliced https page is break the SSL/TLS process.

The event will be logged but the user's browser will behave in different ways there.

No. I just gave up on it. There was another package being developed that I tinkered with for a bit but it never showed up in the repo so I never moved to it. Any SSL intercept is a MITM attack. It works in our client's Sonicwall units without issue (except for the DOJ) by just a checkbox. I'd put so much time into trying to get this working I just gave up. I didn't realize it'd been 2 years since I last tried getting this working.
