Web filtering https option in UTM console possibly mislabeled.

Is it possible that the check box that I have outlined in red below is labeled backwards:

Just as a matter of opinion, good UI should NOT include the word 'not' in the description of a check box.  Additionally, I think this box should be labeled 'Proxy https  traffic in transparent mode' anyway, because that is the way the UTM is acting, i.e. with the box checked https traffic is being proxied by the UTM in transparent mode and with the box unchecked https traffic is NOT being proxied in transparent mode.  If the box is indeed labeled backwards it can cause a great deal of confusion.

thanks,

Richard

  • Hi Richard,

    It is not a typo, this option does indeed provide you the ability to disable web filtering for all HTTPS traffic when on Transparent Mode. 

    Could you confirm what you mean when you say that "with the box checked https traffic is being proxied by the UTM in transparent mode and with the box unchecked https traffic is NOT being proxied in transparent mode"

    If you mean that with this option enabled, you are able to reach https sites with no problems and with it disabled, you are unable to. That is simply due to the proxy being disabled, so all https traffic is just allowed to flow. To transparently filter HTTPS traffic, you must enable Decrypt & Scan which requires deploying the Proxy CA: Sophos UTM: How to Deploy the Web Protection Proxy CA

    Please let me know if you have any questions.

    Thanks,
    Karlos

  • Hi Karlos,

    Thanks for your explanation, but I still think that check box is mislabeled and your last paragraph helps me confirm it.  Here's what I have going on, I am using a commercial application that uses HTTPS and it has been working for years with that check box checked, i.e. if we assume the box is currently labeled correctly, having the check box checked means "Do not proxy HTTPS traffic in transparent mode" implying that the proxy will NOT be involved in HTTPS.  I know the application's destination server is AWS (Amazon Web Services).  The application broke on it's own on approximately 1/18/2018 which I believe coincided with Amazon removing support for flawed security protocol TLS 1.1 (the server at Amazon is currently ONLY supporting TLS 1.2).

    I believe there are some community requests and articles indicating that the Sophos Web proxy is NOT yet supporting TLS 1.2.  So, what I know is I can un-check this box, which to me means disable this option (but, the option is described with the word 'not' in it, so un-checking this box would mean to enable the proxy for HTTPS.  As of 1/18/2018, un-checking this box makes the application work, not the other way around.   I can simply check the box and the application will NOT work, un-check the box and the application works again.  If anyone is having trouble following this paragraph it's likely because the check box was labeled with the word 'not' in it which I think is not the best practice.  Contrast to if the check box was labeled 'Proxy HTTPS traffic in transparent mode' versus how it is currently labeled, checking the box would clearly mean the proxy would be involved in HTTPS, un-checking, i.e. disabling the option, would mean the proxy would NOT be involved in HTTPS traffic.  I am confident the application works with TLS 1.2 and confirmed this by temporarily putting a very old OTS router temporarily in place (a router that would not have provided a Web proxy) and the application worked.

    In summary, I have an application that has worked for years with this box checked, now I have to un-check the box for the application to work.  Just the opposite case of what you described in your last paragraph.

    thanks,

    Richard

  • Yes, tail -f /var/log/http.log would indeed do the trick, Richard.

    I still think there' something else going on.

  • Bob,
     
    I don’t mind collecting and sharing a tail of the http.log. However, isn’t it wasting our time since I mentioned that the internal IP address of the camera doesn’t appear in any of the logs?  I only mentioned the tail so you could help show me when the proxy is getting involved in https and when it is not. Is it documented anywhere?
     
    Thanks again,
    Richard
  • Like I said, Richard, I think there's something else going on with the camera.  You can see if a PC browser's HTTPS traffic is handled by the Proxy depending on whether you check that box.  Give WebAdmin and the configuration daemon a few minutes to complete rewriting the code that runs the UTM before you test a change - I would expect this particular change to take place quickly, but I haven't tested it.

    Cheers - Bob

  • Bob, Karlos,

    Thanks for your replies and patience.  After further research I have concluded that the box is indeed labeled the way it is currently working and it is the proxy that is now allowing blinkforhome to work for me.  I was misled by at least three items: 1. I determined that AWS is now only supporting TLS 1.2 so it was difficult for me to reconcile why/how a very old Engenius wireless router allowed the cameras to work again (I can only conjecture that Amazon still has a common cipher active with the old router, and oh BTW, with the older cipher settings on the UTM).  2.  I had accidentally typed the wrong subnet prefix for the camera, so the camera's IP was appearing in the http.log after all.  3. I was not able to speak with a support engineer at Blink until late in the game and I'm not sure he was confident one way or the other about TLS 1.2 support.

    I apologize, you were correct all along.  When the box is NOT checked, then proxy gets involved in https.  I do stand by the box should be relabeled to "Proxy HTTPS in transparent mode" and the code should be changed to match, but that is an interface opinion and at least the setting currently operates according to the current wording.

    One strange anomaly, I did see a stray 'url=https://.....' a couple of minutes or so after I had checked the box and hit apply.  But, maybe that was just during transition to the other mode.  What is weird about that is checking the box and hitting the apply pretty much instantaneously breaks the cameras.  So, the problem is still a mystery since I had this box checked for at least a couple of years.  I am open to any ideas and will continue to talk with blink; I would think with the size of their customer base there would be a lot of complaints, but I would say by far most of their customers are using OTS cheap routers.  What settings are in play when the box is checked, is that just straight NATing?

    thanks,

    Richard

  • When the box is checked, it's the firewall rules that determine if the traffic passes and then, yes, you do need a Masquerading rule for the traffic.

  • Bob,

    Masquerading for that VLAN (3) is and has been in place all along.  So, there is some other reason why with the box checked the camera can no longer upload to AWS.  Is there a log snippet I can get you that may help to debug?

    thanks,

    Richard

  • Hey Richard,

    Thanks for the update. As Bob mentioned, checking that box then passes the responsibility over to the Firewall to either allow or block the traffic. Have you filtered your firewall logs by the Camera IP/subnet to see whether packets are being dropped? You could also look into your IPS logs, if it's enabled. 

    Cheers,
    Karlos

  • Hi Karlos,

    When the box is checked, the only logs where the camera's IP address appears are as follows:

    1. confd-debug.log

    2. confd.log

    3. dhcpd.log

    4. http.log

    5. system.log

    I don't think any of the logs will help us; number 1, 2, and 5 mention the IP only for license tracking; 3 has to do with the dhcp lease of the camera's IP; 4 has no log lines after I checked the box for this test.  I can use tcpdump to capture a trace from the camera, but I cannot determine why the connection terminates prematurely.  All of this worked prior to 1/18/2018.

    From the Linux command line or the Web interface is there a way I can tell if any threat patterns were updated around that date?  I do not have automatic firmware update enabled and I don't recall updating the firmware around 1/18.

    thanks,

    Richard

  • So, we don't see any Snort signature updates and since the accesses weren't going through the Proxy before, no anti-virus was being applied.  That just leaves aptp - Application Control.  Are there any differences in what's in that log on 1/16 and 1/19?

    Cheers - Bob

  • Bob,

    Both of those logs are zero length.

    thanks,

    Richard

  • If Sophos Support can't help, it may be time to get some backups off the box and reload from ISO.  Before doing that, try restoring a backup from before the problem began - don't forget to make a new backup first!

    Cheers - Bob

  • Thanks Bob.  I had already tried a restore some time ago, didn't help.  I do not have a backup of the entire filesystem and wish I did.  Maybe if I get some time I will save off an image and try from the ISO,  but I really don't want to do that if at all possible.  Maybe Sophos support will have some ideas.  Checking or not checking that box shouldn't impact whether the https communication works or not (unless, of course the site is explicitly and purposely filtered).  Who knows what changed?  Potentially something on AWS which is a complex environment where regional servers are scattered all of the world.  But, it's not great for Sophos since cheap OTS routers are not having problems.

  • Any updates on this mystery, Richard?

  • Hi Bob,

    Thanks for checking back, but no updates yet.  I was hoping Sophos support would join in at some point.

    I'm confident there is an issue, but I'm at a loss as to what it is.  Applications should work with or without proxy. Blinkforhome worked for at least two years without proxy, now (as of approximately 1/18/2018) https proxy is required to work.  Check the 'Do not proxy https...' box it will break Blinkforhome, i.e. uploads of photos and video to AWS.  My workaround for now is to uncheck the box.

    thanks,

    Richard
