@madbrain said in Netflix buffering with 3 WANs:
sticky
Unfortunately, using sticky connections effecttively disables load balancing.
Here is a traffic graph without sticky connections :

And here is the graph with sticky connections enabled :

As you can see, only the first WAN, Comcast gets used. The overall speed is also much lower.
Even more surprising, the bandwidth on Comcast is only about half what it was without sticky connections - 700 Mbps vs 1400 Mbps.
This may be due additional overhead in pfSense for sticky connections. Although this is hard to believe since my pfSense is running an AMD 5700g APU.
Indeed, when I repeated the test, I got different results each time. Sometimes hitting 1.4 Gbps, others not.
The interesting part is that I tried to run speedtest from 3 different hosts - 2 on LAN, plus my smartphone, and still only the Comcast WAN got used. So it seems "use sticky connections" really disables load balancing effectively.
