I didn’t see many examples fro RouterOS 6 so I thought I could share mine.
We’ve been testing this configuration for a month and seems to do its job. It was tested on a RB2011 with WAN on eth1, and different LANs on the rest of the interfaces (eth2 - 192.168.2.0/24 …)
If you detect any mistake or want to suggest improvements feel free to do it
# Sample configuration by Carlos Corcoles Toledo
# Only the "firewall mangle" and queue related sections are shown
# Numbers calculated for connection with 30Mbps download and 6Mbps upload with around 100 concurrent users
# The idea is to share the bandwidth equally amongst the users in case of saturation
# The limit-at values are calculated with 100 users in mind (total bandwidth divided by 100)
# For different download and upload speeds change the numbers accordingly
# Mark the connections. Internal traffic has no limit
/ip firewall mangle

# Slightly changed default pcq queue sizes
/queue type
add kind=pcq name=pcq-descargas pcq-classifier=dst-address pcq-limit=100 \
pcq-total-limit=10000
add kind=pcq name=pcq-uploads pcq-classifier=src-address pcq-limit=100 \
pcq-total-limit=10000
# We create new global upload and download limits
/queue tree
add max-limit=29M name=qosdownload parent=global queue=default
add max-limit=5500k name=qosupload parent=global queue=default
# Then we set the limits for each user
add limit-at=55k max-limit=5500k name=limitupload packet-mark=packmarkupload \
parent=qosupload queue=pcq-uploads
add limit-at=290k max-limit=29M name=limitdownload packet-mark=packmarkdownload \
parent=qosdownload queue=pcq-descargas
Only one thing, why the 10000 in that line:
/queue type
add kind=pcq name=pcq-descargas pcq-classifier=dst-address pcq-limit=100 pcq-total-limit=10000
add kind=pcq name=pcq-uploads pcq-classifier=src-address pcq-limit=100 pcq-total-limit=10000
I did not understand that part, because it doesnt match any values like
