I think that I find the 'error'.

Quota follows same rules that limit?

https://wiki.nftables.org/wiki-nftables/index.php/Rate_limiting_matchings

If it's correct it should be good to alert users that ares reading https://wiki.nftables.org/wiki-nftables/index.php/Quotas that Quotas follow same rules that limit.... 80)

best regards

Assunto: nftables - quota isn't working?

Hi all

Reading https://wiki.nftables.org/wiki-nftables/index.php/Quotas

I have been testing quota but I have a doubt.

a) If I use this rule below , quota reaches its value, but download continues.

insert rule inet filter FORWARD ip daddr 192.168.10.11 quota until 2 mbytes counter accept comment "paulo-quota"

nft list ruleset | grep 'paulo-quota'
ip daddr 192.168.10.11 quota 2 mbytes used 2 mbytes counter packets 1074 bytes 2094663 accept comment "paulo-quota"

b) But if I invert logic, download stops.

insert rule inet filter FORWARD ip daddr 192.168.10.11 quota over 2 mbytes counter drop comment "paulo-quota"

debian-10.10.0-amd64-netinst.iso
https://gemmei.ftp.acc.umu.se/debian-cd/current/amd64/iso-cd/debian-10.10.0-amd64-netinst.iso
0 B/s - 22,9 MB de 336 MB

Should a) have the same result as b) ?

Ubuntu 20.04.2
5.4.0-47-generic #51-Ubuntu SMP
nftables 0.9.3-2

Thanks in advanced
