I have a Peplink 20.
I want to reduce jitter, and notice that when traffic on a WAN goes up, jitter on that WAN goes up too.
To test this, I just started downloading tons of files and watching a couple videos. Then I noticed that my download bandwidth on my primary WAN went far higher than what I set as the download bandwidth (set from the Network > WAN page). I assumed that this setting was also used for QoS (what difference does QoS make if we are overflowing our connection?), but now when I look at the manual again I am thinking that maybe this is only used for load balancing? If that is the case, then how does QoS work?
My outbound policy has several rules (using the Enforced algorithm) simply for me to monitor jitter from within the LAN (so that I can test this every 5 minutes, and I know which WAN is used so I can compare the jitter).
Then I have a rule of algorithm Priority with WAN 1 as the top priority.
My expected behavior on this would be that WAN 1 is used exclusively (aside from those enforced rules that are set solely from one-to-one from an IP in my LAN to an IP out on the internet) up to the speed settings I set from the Network > WAN page and roll over to WAN 2 if WAN 1 fails. Is that not correct?
If not, how do I configure my Peplink 20 to do that (use WAN 1 exclusively aside from those few enforced rules up to a speed I set, and fail over to WAN 2 if WAN 1 fails)?
