Unstable Sophos UTM 9 - please help

Hi,

I'm running Sophos UTM 9 on an older HP Pavillion PC. I'm not sure about the specs but it works fine. Internet/LAN is stable. However, this PC is kinda noisy due to HDD and fans so I'm trying to get something more quiet and modern to run Sophos on.

First I tried installing Sophos on a Mintbox2: http://www.fit-pc.com/web/products/mintbox/mintbox-specifications/

Then I tried using Sophos on a Dell Optiplex 980: https://www.cnet.com/products/dell-optiplex-980-core-i5-650-3-2-ghz-4-gb-320-gb-4688405/specs/

I've installed SSD in both those machines. However, none of them can be used because WAN/LAN is completely unstable. WAN-link keeps going up and down and the network speed is slow. Whenever you do a line test the WAN-link goes completely down and LAN is generally unstable.

Does anyone have a clue why Sophos UTM 9 works on an older HP Pavillion but not on either the Mintbox2 or the Dell Optiplex?

  • I've given up on the UTM. In my opinion this software is extremely picky on its NICs. As a last attempt I tried a brand new D-Link network card instead of the Intel PRO 1000GT in the Dell Optiplex, but with the same poor result. (and yes. I did a reinstall of the UTM software after changing the NIC, just to be sure).

    So I gave Sophos XG a shot and turns out it works perfectly on the same Dell Optiplex, whereas the UTM was unusable. I do not at all like the XG user interface compared to the UTM, but I'd rather have something I can use.

    Thanks for every contribution in this thread.
