Can’t get the shaper on OPNsense to work.

[robert.haugen@gmail.com]

I want the LAN network to have priority for download traffic.
When the network is not congested, the GUEST network should still have full speed.
However, when both LAN and GUEST are heavily used, LAN should receive significantly higher priority.

I've tried all combinations of Pipes, Queues, and Rules without success.

Reference:
https://docs.opnsense.org/manual/how-tos/shaper_prioritize_using_queues.html

For testing, I'm using two Debian Linux clients — one on LAN and one on GUEST — running the "Speedtest by Ookla" CLI tool.

You need the pipe first as in the howto, with the total available WAN bandwidth.

Then you need two queues for LAN and GUEST referencing that same pipe and weights to define the relative priorities as in the howto.

Last, you define the LAN and GUEST rules referencing the resprective queue. They both use the WAN interface, apart from that they have for the LAN rule:

interface = WAN
proto = ip
source = any
src-port = any
destination = 192.168.x.0/24 (whatever your LAN network has)
dst-port = any
target = LAN-Queue

and for the GUEST rule:

interface = WAN
proto = ip
source = any
src-port = any
destination = 192.168.y.0/24 (whatever your GUEST network uses)
dst-port = any
target = GUEST-Queue

You probably used the LAN and GUEST interfaces in the rules, that will not work.

Thanks.

Using IPv6, I think the client is communicating with the default gateway using its link-local address. The link-local subnet is the same on both GUEST and LAN:

fe80::/64

Could that be the culprit?

Priority in QoS is feature, where a packet of a certain application will leave the router sooner than the packet from any other application.

This by nature is not possible.

IPFW which is the underlying feature used for Shaping, doesn't have a scheduler that allows to set traffic priority or a priority queue. What you can do, is to set weights using a weight based scheduler to allocate a ratio of a BW to a specific application.
