Next EAP release date?

see magic happens. LOL

Ian

So ? Installed since few hours ? You found any magic running already ?

As far as I am concerned Microsoft Outlook still refuses to work with DPI activated.

DPI is still no-go.

IMAPS does not work with 17.5.9 or v18 EAP, the funny part is most sites work and SMTPS  with the XG CA. I am wrong about smtp, it does not work with mac mail.

What magic did I find, the major bug in ATP appears to have been fixed, now just a minor issue. DPI, I haven't seriously tried so far.

Now waiting until tomorrow's daily reports arrive.

Hi,

I've found some "new magic" on EAP 3 Refresh,

It's finally better to debug SSL/TLS erros on XG. *Overall logs still sucks.

Snort isn't killing my CPU anymore, It's using a reasonable amount of it, also something interesting: On multiple connections, snort is seamlessly sharing the load between the cores perfectly, which is impressive, something changed for good on it.
There's still some quirks and errors with DPI (mostly HTTPS), but It's with Firefox, on chrome it works perfectly now.

They changed how to create NAT rules, for good. (also made a wizard for DNAT)

I believe It has Ilferrara who gave the ideia here. Thank you!

One thing that apparently still hasn't been fixed is the new Flow Monitor, still sucks, and shows values that makes no sense.

*Dumb mistake made by myself.

Thanks!

Hi Prism,

Could you give some more specific detail on what you are seeing with Firefox with DPI enabled?

- Are the problems visible when browsing, or are you just seeing errors being logged?

- If the problems are visible when browsing, do you see errors being logged in the SSL/TLS log in log viewer? If so, could you send (in direct message) example log lines - the detail from the detailed log view would be most helpful.

- Are the problems happening with specific websites or are they happening across a range of sites?

- Are you running on Windows, Mac or Linux?

- In Firefox, enter 'about:config' in the address bar, click through the warning, and then search for security.ssl.enable_false_start. Is this set to 'true'? If you change the setting to 'false' do the quirks and errors go away or reduce?

Many thanks,
Rich

We know of many users (including internal Sophos users) who are running Outlook happily with DPI enabled, and would like to get to the bottom of why you're seeing issues where others are not.

Could you please provide more detail about the issue you're seeing with Outlook.

- What operating system are you running, and which version of Outlook? Are you connecting to a local exchange server or to Office 365?

- At what stage does it fail? Does it not connect at all? Or does it connect, but fail completely or partially to retrieve mail? Or something else?

- Do you see any errors under SSL/TLS or Web Filtering in the log viewer that are related to connections?

- Do you have SSL/TLS decryption enabled for this traffic?

Thanks,
Rich

Hi Rich,

I'm sorry that I won't be able to provide logs right now (I will do It later).

Let's start with this:

Already done that before, as I faced some errors with Firefox before, here's the topic.

This fixed a lot of errors I had before, but there's still some others.

The problems are visible, but on XG It doesn't show any errors, it shows as the session has successfully Decrypted. * Only on "SEC_ERROR_REUSED_ISSUER_AND_SERIAL"

I'm getting: "PR_END_OF_FILE_ERROR" on certain websites, just on the first time accessing it, refreshing the page after It and It will load as expected.

I'm also getting a lot of "SEC_ERROR_REUSED_ISSUER_AND_SERIAL" It also depends on the website I'm accessing. Strange enough, this happens sometimes on Chrome, and give me no option to access the website anyway.

As stated before I will provide logs later (I will edit this post).

As stated before, It's only happening with specific websites.

Linux on my computer, and Windows 10 on my notebook.

Thanks!

I am having this issue since v18 EAP1 and this has been investigating by Sophos devs (I exchanged some logs and email with them). The issue is tracked under the NC-51956.

https://community.sophos.com/products/xg-firewall/sfos-eap/sfos-v18-early-access-program/f/feedback-and-issues/115778/using-the-new-dpi-ssl-tsl-linkedin-does-not-open-with-firefox-on-mac

I have tried the FF workaround to disable the ssl component in about:config but doe not help alot.

Please create proper thread and do not use this thread as the topic is totally different.

Regards

Running windows 10, 10.0.18363.592.

Outlook 2010 and Outlook 2013

It takes up to 20 minutes before Outlook connects to Exchange.  After, it works.

In do not see SSL/TLS error.

Any news about date of next release?
