QoS change = broken internet

Hi. Hope I'm posting in the correct group..

I'm trying to change the up and down speed of the external NICs QoS rule. When I make the change, I have no internet connection. Turning the QoS of for that interface has the same effect. Looking at the firewall log, there are a lot more blocks taking place than usual. DNS is also getting blocked then.

Reverting the QoS settings gets the internet back and stops the DNS blocking in the firewall. I am however getting packet loss when doing a ping test from the utm to and external IP. Upload speed is also horrible.

I've tried different NICs (Intel), different cables and disabling every protection feature I could find, but nothing helps

  • Please show a picture of the Edits of the QoS Interface and rule that works.  Also show a picture of the change you made that blocks connection.

    Cheers - Bob

    Hi Bob

    Please see attached here. I don't have any rules yet, only these interface settings

    I've managed to get the settings changed now. First had to turn off the QoS interface, change the settings, turn off the actual interface under Interfaces and wait 1 minute, then turn the interface back on and then turn the QoS interface on. 

    I don't know if it's repeatable. Since I finally got it changed I don't want to test that right now.

    One thing I did notice is that when changing QoS settings, the loading/activity indicator ring at the top of the interface stays active and never stops. Maybe some process getting stuck, or just a glitch in the interface?

    Hi,

    strange error. Just for clarification, you don’t run on SG Hardware, but on a PC base system?

    I normally recommend never selecting 'Limit ...' on the 'Status' tab - what is it that you intended to accomplish with those selections?  I also recommend only selecting 'Upload optimizer' if, and only if, you have no Bandwidth Pools for the interface.  What are the up/down speeds your ISP brings to this connection?

    Cheers - Bob

    Hello Bob,
     
    not directly related to this thread, but could you briefly explain why - never selecting 'Limit ...' on the 'Status' tab?
     
    Best regards,
    Alex

    Because it's a "dull knife" that limits all traffic, Alex.  QoS has the ability to do any desired limiting.  Why pay for bandwidth and then prevent the use of it?

    Hi

    Yes it's a PC based system

  • Everything is still running fine. I'm going to test changing the settings again this weekend and report back.
