Unstable Sophos UTM 9 - please help

Sven David Hildebrandt

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?

    Assumptions and coments

    1/. you installed a second nic in the dell?

    2/. you connected the ssd to the sata port?

    3/. Which mintbox did you purchase?

    4/. what chipsets do they run, are they supported by UTM?

    5/. the dell is a very old model or at least the cpu is.

    1. Yes. I installed a Intel Pro 1000 GT NIC in the Dell

    2. Yes, I've mounted SSDs into both the Dell and the Mintbox and the disks work fine.

    3. Mintbox 2, it's standard config with 4GB RAM, only I've changed the 500GB HDD with and 128GB SSD.

    5. The Dell is old yes, but the HP Pavilion is just as old and works fine.

    4. Mintbox 2: Mobile Intel QM77 Chipset (Panther Point)
    Dell Optiplex: Intel something

    This is Sophos requirements stated by Sophos themselves, and it doesn't say anything about chipset:

    Sophos UTM installs on any dedicated X64 machine, turning it into a fully functional unified threat management firewall. Perfect for that spare machine you have sitting around!

    Minimum Hardware Recommendations

    • 1.5+ GHz processor (dual core+ recommended)
    • 1 GB RAM (2GB strongly recommended)
    • 60 GB hard disk
    • Bootable CD-ROM
    • 2 or more network cards
