Questions about Queues & Priorities…



  • I have an ALIX.2C13 board from Netgate and installed the latest 2.0 Beta on it.

    It is currently successfully load balancing between my DSL and Clearwire modems at home.  :D

    Nice job, guys!  pfSense kicks butt!

    Anyway, traffic shaping…

    I went through the traffic shaper Wizard for one LAN multi WAN.  And it set things up nicely.

    I was looking to do something like this:  http://www.benzedrine.cx/ackpri.html

    And also for pings, since the pings are used to check gateway 'quality' in terms of latency and packet loss.

    I'm not using latency for fail-over, since downloading a large file increases latencies.

    So, was hoping to setup queues to prioritize ping and ACK on each of my gateways.

    The wizard did have an option to make ICMP high priority, which I did.  But what about ACK?

    When I click on the queue graphs, it has qACK on WAN, for example.  Is this already prioritizing ACK, or should I look into trying to implement the technique listed on that blog?

    How large should be qACK's bandwidth depends on the ratio between uplink and downlink bandwidth. In most cases the default setting should be fine.
