How come my Download Bandwidth is Half of what it is when using SOPHOS UTM 9.4 ?

DavidBowman

A very good day to you Sir !

I hope you are doing Great Sir !

I am a total newbie and have just installed SOPHOS UTM 4.3 on a APU2C4 Hardware

Why is it when I run the "Internet Speed Test" through my original Asus router I can get up to 99mbps,

But when I run the "Internet Speed Test" thought my newly installed SOPHOS UTM 4.3 Firewall I can only get up to 50mbps ???

How can I configure SOPHOS to use up all the available Download and Upload Bandwidth of my ISP ?

Hope to hear from you soon.

Thank you very much for your time and kind help.

    Hi David,

    Thanks for choosing Sophos.

    Before moving further, let us know if the WAN ISP line is directly connected to UTM or through an intermediate device? If there is an intermediate device, please take SSH to UTM with root privilages, please refer this link here. Next, run the command ifconfig and check if there are any error and dropped packets discovered on any interface. If you face any type of difficulty in understanding the output please post a screenshot here. 

    If the ISP line is directly connected to UTM, run the command: wget --no-check-certificate -O - https://raw.github.com/sivel/speedtest-cli/master/speedtest_cli.py | python

    Post the output or verify the speed captured directly on the UTM. Also, post the result on ifconfig whilst the ISP is directly connected to UTM.

    Thanks

    Also, he should check #1 and #7 in Rulz to see if there are other issues.

    PS Can you suggest a new rule or a change to an existing one?

    Can also try temporarily disabling the Intrusion Prevention System (Snort). The IPS uses a lot of CPU power and can be a bottleneck, less so now with recent updates.

    Also the web proxy will give slow results on bandwidth speed tests.
