Anyone else seeing this? Page load failures, sudden connectivity drops? UTM9

JoeChurch

I'm running the latest build of UTM 9 home and have started to notice some strange behavior.  It happens mostly to wireless clients on my network, hard wired devices don't seem to experience the issue.  So think mobile devices, iphones and iPads. 

What will happen is that as I'm browsing a web page in the mobile browser, the pages suddenly stop loading.  I can't get anywhere, refreshes don't work and I have to drop off the wifi to LTE in order to load the page.  Usually going back on wifi will have things running again for a short time until it happens again.  Same thing running games and apps from mobile devices, you're in a network game and suddenly you get disconnected and it says it lost network connection in the game.  The device is still on wifi and you can ping the gateway but you can't get anywhere out to the internet.  

This is starting to drive me crazy because I can't see to find anything in the logs on the UTM that shows what the issue is.  I know its possible the issue might be with my wifi, but its an enterprise grade wifi system and has been working perfectly with no changes for several years.  I am upgrading the hardware for wireless again this week, so that will be interesting to see if it helps.  But I don't think its related to the wifi hardware.  

Any ideas from the UTM side of things where I could check basic configuration options or enable some kind of extra logging to troubleshoot?  

One observation I had so far is that when my connection drops I can manually enter the proxy settings in my wireless profile on the device and point it at the UTM on port 8080 and then it works again for a while.  But the same thing ultimately happens with those settings as well.  Its happening on multiple devices over wifi, mostly apple devices.  So maybe there is some sort of apple specific setting I can check?  

I'm using the transparent proxy on an internal trusted network.  Everything else is rock solid except for this strange sporadic connectivity issue.  I should also mention that laptops connected to the same wifi do not experience a problem like the mobile devices do.

  • After unsuccessfully trying to resolve the issue I ended up shutting down the UTM VM's and fired up the XG Firewall VM's.  I have both and can switch between the two fairly easily.  I may just stuck with the XG for now, I've invested a lot of time lately self-learning the config and tricks to get things working.  I've managed to work out most of the issues with the XG and have a nicely working system.  I still run into the odd hiccup now and then and end up having to turn off features that end up causing a problem.

    Joe, the solution is to simply downgrade UTM to the 6/26 update... simple & straightforward

    I wouldn't call that a solution, its more like a bandaid or a workaround.  Its also a PIA and not something that should be needed from a reputable vendor like Sophos.

    My guess is you're not a paid licensee, therefore that opinion is quite hubristic.  If you are a paid licensee, then contact Sophos Support and they'll troubleshoot the issue with you via phone.

    • Corporate sponsors for free OSes do so for at least one, or both, of the two following reasons: Either there's a benefit to the security of their corporate customers (i.e. malware reporting, possible intrusions and their originating countries, etc.), and/or crucial feedback about stability is garnished.
      • Another example of this model is FreeNAS, whose corporate sponsor is iXsystems and their version of FreeNAS, TrueNAS (granted FreeNAS is open source, whereas Sophos is built upon OpenSUSE and some open source programs)

    I'm not sure I follow how a reinstall is such an inconvenience... it takes what, 15 minutes to do?  Once done, you import your configuration backup and you're good to go.

    • Perhaps I have the wrong perspective, however bugs happen from time to time; and while some are quite minimal, others will be far more serious.  Programmers and software engineers are human just like you and I, and as such, occasionally make mistakes.
