Hello all!

​

I have the next config. Keep in mind that VLAN20 is the WAN and ISP is the bridge where my service VLANS live:

​

/ip firewall mangle
  chain=prerouting action=mark-connection new-connection-mark=conn-30.30 passthrough=yes src-address=172.16.71.0/24
  chain=prerouting action=mark-packet new-packet-mark=pack-30.30 passthrough=no connection-mark=conn-30.30

 /queue type
  name="DL_30M" kind=pcq pcq-rate=30M pcq-limit=50KiB pcq-classifier=dst-address pcq-total-limit=2000KiB pcq-burst-rate=0 pcq-burst-threshold=0 pcq-burst-time=10s pcq-src-address-mask=32 pcq-dst-address-mask=32 pcq-src-address6-mask=128 pcq-dst-address6-mask=128 
  name="UL_30M" kind=pcq pcq-rate=30M pcq-limit=50KiB pcq-classifier=src-address pcq-total-limit=2000KiB pcq-burst-rate=0 pcq-burst-threshold=0 pcq-burst-time=10s pcq-src-address-mask=32 pcq-dst-address-mask=32 pcq-src-address6-mask=128 pcq-dst-address6-mask=128

/queue tree
  name="BAJADA" parent=ISP packet-mark="" limit-at=0 queue=default-small priority=8 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s bucket-size=0.1 
  name="SUBIDA" parent=VLAN 20 packet-mark="" limit-at=0 queue=default-small priority=8 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s bucket-size=0.1
  name="BAJADA_30M" parent=BAJADA packet-mark=pack-30.30 limit-at=0 queue=default-small priority=8 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s bucket-size=0.1 
  name="SUBIDA_30M" parent=SUBIDA packet-mark=pack-30.30 limit-at=0 queue=UL_30M priority=8 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s bucket-size=0.1

I've done this config a lot of times in previous versions of RoS 6 and it worked perfectly. Now I'm using 7.10.2 and the limit works only in upload. Download keeps unlimited. Am I doing something wrong?

​

Thanks in advance.

=====EDIT====

Okay guys. I found something interesting. Maybe this is a bug?

I've been making a lot of tests to find out what is the problem so I can solve it.
I found that, when I'm downloading, Mangle rule Statistics only show a few kbps (even when downloading @ 50Mbps). So I thought: maybe I did something wrong in the mangle, but checked and checked again and everything is fine.
So I say: let sniff packets to see if maybe RoS7 handles this in other way.
I turn on packet sniffing, and inmediately, mangle statistics start to show the real traffic and queues start to work. I disable packet sniffing, statistics go back to few Kbps and queues stop limiting.
Here a few pics (while downloading from the client):

1. Packet sniffer stopped:

​

Packet sniffer stopped -> Mangle shows no relevant traffic

1. Packet sniffer running:

​

Packet sniffer running -> Mangle show real traffic and queues work both up and download.

​

Am I missing something or could this really be a bug?

Thanks.
