Internet choking when downloading anything.

Cyber Army

Hi all.

I am unable to download anything since i have installed sophos utm 9.

If i am downloading through a download manager, or using sftp via filezilla/ftp client, the downloads will start, but then the speeds will start dropping or the entire internet connection destabilizes, or disconnects.

Its as if the downloads or the internet gets choked when I begin downloading. I have to restart the sophos server in order for the internet to function normally.

What am i doing wrong? What settings do i need to enable?

    Enable QoS on your interface, set the download and upload speed correctly. and this will take care of the rest. Try turning off limit uplink and downlink and just have upload optomizer and see if that makes a difference, but ultimately set all 3.

    Thanks for your replies.

    I've tried this, and still it doesnt work.

    I tried to run a speed test to get a proper uplink and downlink to add to the External WAN interface, but the speed test wouldnt go through either.

    Something really strange is going on with my internet since ive installed sophos utm9

    I am sure that there are settings i need to enable, and it doesnt come out of the box.

    So some basic questions.. 

    How do i find my uplink and downlink speed? Use speedtest and get that info from there? My speedtest until just before i install utm 9 used to show 350mb/sec download and 30 mb/sec upload. Is this the value i should add to the interface?

     

    I didnt get this part where u adviced... "Try turning off limit uplink and downlink and just have upload optomizer and see if that makes a difference, but ultimately set all 3."

    Do i need to check all three in the end with proper downlink and uplink added?

    Unless there's a financial/business reason to limit Uplink or Downlink, I wouldn't use them.  If I'm controlling Uplink with Multipath rules, I don't activate 'Upload optimizer'.

    To see the raw speed results for the UTM, first load speedtest as root by copying the following lines to the command line :

    cd /home
    wget https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py --no-check-certificate

    Now, run the test, first with IPS off, and then with it on.  Paste the following block at the command line:

    cc set ips status 0
    sleep 15s
    python speedtest.py
    cc set ips status 1
    sleep 30s
    python speedtest.py

    Please share your results.

    Cheers - Bob
