Configure minimum allowed TLS version to improve security.

WAF protection and authentication policy templates were added for common Microsoft services for protection and authentication.

True File Type Scanning to be able to block uploads based on MIME type.

WAF Proxy Protocol Support to use the client IP info inside the ProxyProtocol header to make policy decisions and improve logging.

  • Sophos Sandstorm

Datacenter location selection for Sophos Sandstorm without relying on DNS based location detection.

Scan exceptions for Sophos Sandstorm to exclude specific filetypes from being sent to Sophos Sandstorm analysis.


RESTful API to configure Sophos UTM 9.

  • Base System

Certificate Expiration Notification 30 days before expiration date via WebAdmin and e-Mail to be able to react early on certificate renewal.

Support Access with SSH is extending the existing Support Access feature.

  • In reply to jag2000:

    Try posting the DHCP log here? :-)

  • In reply to twister5800:

    i will have to do that later. i had to move my network over to my Meraki MX64 because its impacting work.

  • In reply to twister5800:

    How does this occur ? Does it happen directly after an upgrade? Or does it occur after a period of time? Would this affect a fresh install of 9.5?

    Also was the fix permanent or did the issue resurface?

    How many virtual hosts did this customer have? Was this a big deploymemt of WAF? Have any of your other customers had issues with waf or is this customer the biggest?

    I'm about to deploy waf for 300 websites with 5 back-end hosts, and we are starting fresh with 9.5 on a pair of sg430. So I want to understand thr circumstances behind how your issue happenend.

  • WAF Exchange Server 2003

    Hi after the upgrade on a SG135 UTM Outlook Web access stopped working.

    Ther Exchange server is part of SBS 2003. after the upgrade we get this message

    Proxy Error

    The proxy server received an invalid response from an upstream server.
    The proxy server could not handle the request GET /exchange.

    Reason: Error reading from remote server

    2017:05:17-22:54:00 COLORFOTO-UTM01 reverseproxy: [Wed May 17 22:54:00.575738 2017] [proxy_http:error] [pid 19032:tid 3836775280] (103)Software caused connection abort: [client] AH01102: error reading status line from remote server

    I know its a pretty old server and we are in the process of upgrading to 2016, but meanwhile everyone stopped to get email on their mobiles and tablets.
    This just happend after the upgrade.


    Thanks in advance



  • In reply to StealthyM:

    It did occur 4 days after upgrade, have not seen this on fresh installs.

    As I did implement the fix yesterday, I am not sure if it's permanent yet :-)

    They have 10 sites and 5 webservers behind WAF and are not the biggest.

    I will make a support case today to make them look at it :-)

  • In reply to JamesGolden:


    Was that something that 9.5 turned on or was something I may have turned on before but didn't see any issues with? 


    The default setting is "Off", so it looks like you may have made the change. We're still looking into the root cause for this and it seems to only happen for systems that have received a fair amount of up2dates. With a fresh install this issue is not reproducible.

  • In reply to HeikoHund:

    Heikohund, that's not entirely true.

    In the start uf UTM 9 (i think) the Default was "Auto" and i assume if you upgrade the appliance and never do a reinstall this setting will be kept.


    So maybe, JamesGolden, you have an older Installation and because of that the setting is "Auto".




  • In reply to HeikoHund:

    I haven't upgraded to 9.5 yet, but have had the UTM for a while and only ever done up2dates, no fresh install.

    I've never been into HA but went in to have a look, mine was set to Automatic Configuration.  This must at some point have been the default configuration.

  • In reply to steveatkinson:

    That the same on our UTM.

    The UTM is now 2,5 years old and has all the time only be updated.

    This feature must be on Auto since then.

    Nevertheless it is important that there is a workaround.

    Everything else they can correct for the next update. 

  • Still only seeing this being offered to 1 of my 4 UTM's, I guess this is a very staged/slow rollout??

  • In reply to maxsecobj:

    I haven't seen it on any of the UTMs I manage yet. For mine, I downloaded the up2date file and installed manually.

  • Hi Guys,

    Regarding NUTM-7586. Does certificate has to be recreated and pushed to endpoints after we upgrade the firmware to 9.500?

  • In reply to Andrzej Zakrzewski:

    Does it allow you to do a fresh install on a machine that doesnt have a VGA connection available?

  • In reply to Jeff Siegel:

    Anyone experienced the same problem as described here?

    Keen to update to 9.5 but very wary given the reports of issues.
