Squid3-dev blocks Windows update and other updates

[marian78]

try that, not working for me. Maybe missing some more domains….

[Cino]

maybe this will help for the domain list?

[marian78]

thx sir, but i dont know how set this type of domain: *.update.microsoft.com

In squid i needed strictly setup all domain or it can use * ?

[cwagz]

I have not been able to get this to work either for Windows update.  I did get minecraft working with this method.  Is it possible to use Windows update with HTTPS transparent proxy?

[marcelloc]

Squid wildcard is a . instead of *

If you try it on acls, just try to remove * and keep .update.microsoft.com

[marian78]

thx sir, i try that, hope that will work.  ;)

Thanks

I generated a tcpdump when this was happening and poked around the contents.  I found the URL fe2.update.microsoft.com

I added that URL AND windowsupdate.microsoft.com to my squid.conf (with ssl_bump none as well for each) it seems to be updating now

Hope it helps.

acl windowsupdate dstdomain windowsupdate.microsoft.com
acl windowsupdate dstdomain update.microsoft.com
acl windowsupdate dstdomain download.windowsupdate.com
…

Could you not just use .microsoft.com, .windowsupdate.com and .windows.com to replace all of that?

I've played with Squid3 dynamic caching with Windows Update and I always ended up in a situation where it would download the entire file for every segment it's trying to download.  100 MB of patches required downloading many gigabytes of data, as each segment request would cause the entire file to be downloaded again and again.  My traffic graph would show my WAN being fully saturated for an hour or more and hardly anything coming in to LAN from Squid.

I have more than 70 pcs and i have to fix this urgently, any clue ?

For that many users, why not run WSUS?

Hi, :)
So with ssl filtering, windows update does not want to do this. There in there a manipulation to do to solve this problem.
Sorry for my bad english  ;D

[Abhishek]

I am also facing same issue as reported by poster , if any one have solution to this kindly update this thread ,if i bypass source Ip from proxy server settings i am able to update

[aGeekhere]

This was a main reason why I switch to a wpad.

[Abhishek]

@aGeekHere:

This was a main reason why I switch to a wpad.

So are you telling moving from transparent proxy to non transparent proxy will fix my issue ?

[aGeekhere]

I could not get windows updates to work through HTTPS/SSL interception, and dealing with the CA were a pain.

Windows updates using wpad with squid proxy works.

[Abhishek]

so u disabled Https interception ?    i have no issue deploying cert since i am using AD gpmc

[aGeekhere]

You first have to decide if you want to use a transparent proxy or non transparent proxy with wpad

If you want to try using non transparent proxy with wpad here are a few links
https://doc.pfsense.org/index.php/WPAD_Autoconfigure_for_Squid
https://forum.pfsense.org/index.php?topic=93060.0

Note: non transparent proxy with wpad you disable HTTPS/SSL interception and Transparent HTTP proxy.

Let me know if you get stuck

[Abhishek]

So i cant use Https inspection with wpad ?  As far as i understood wpad is a method of delivering proxy server info such as IP address and port number so we don't need to manually configure all client PC's proxy serttings manually in Non Transparent proxy case

IF using transparent proxy there is no need of configuring wpad

[aGeekhere]

So i cant use Https inspection with wpad

wpad is only used to auto configure a non transparent proxy.

transparent proxy there is no need of configuring wpad

You cannot have both.

You can't use the HTTPS Interception feature of pfSense because it goes along with Transparent mode.  If you use an explicit proxy (not transparent) and WPAD auto-detection, then you don't need to worry about certs or group policy.  You will still be able to filter HTTPS streams and your users won't get a browser warning.  The only glitch is that some mobiles, specifically Android, don't do WPAD so those users must manually configure the proxy.

The issue with the actual version of squid for pfsense is , that the acl "ssl::server_name" isnt available.

The available acl dstdomain shouldnt be used for that, because the information that dstdomain tries to compare are encrypted at these moment.

You could read the description http://lists.squid-cache.org/pipermail/squid-users/2015-July/004429.html

Another issue with Windows Update is , that Microsoft use self signed certificate that are not signed by VeriSign.
There would be 2 solutions for the 2nd issue , ignoring cert errors or import the certificate.
