In the WUI, On Network (others) → firewallhits Graph, I see a value of zero for Average on the NewNotSYN row. However, the values for Maximal and Minimal on that row are both greater than zero. Is that a bug or could someone explain how the average is less than the minimal?
Hi,
this is almost certainly a bug - thanks for catching it. 
Would you mind opening a bug at https://bugzilla.ipfire.org/ (your login credentials work there as well) so we can keep track of it?
Thanks, and best regards,
Peter Müller
Merci.
