MultiWAN tier setup (different speeds)

costasppc · Jul 23, 2017, 9:18 PM

hello,

In a client, we have 3 WANS, 2 VDSL x50 Mbps (5 upload) and one ADSL ~18 Mbps. The client had a TP-Link Load Balancer before pfsense, and he was using speedtest.net app to check the combined speed. With the old lb he had 100+ Mbps download and 10 upload, all the time.
Using pfsense in an APU.1D4 - 4GB, msata along with a Ubiquiti ES-48-Lite EdgeSwitch (2 WANs setup as VLAN in OPT port), he gets around 75/8 (with all WANs grouped as tier 1). Using the fast WANs only as tier 1 he gets less all the time (60-65).

Is there a way to set the tiers to achieve all the speed of the 3 WANs (at least at speedtest, even though I know you will say its not accurate enough).

Best regards

Run a tcpdump and check if all the wans are actually used.

Thank you,

No need, they are used, I can see it in the Dashboard. Also, the change is visible when you put the 3rd WAN along with the others.

With different WAN speeds you use "Weight" to "distribute" the traffic according to each WAN speed, not "Tier" ;)

Correct, thank you very much!

Based on the document and other search, I see examples only for 2 uneven WANs.
In my case, since the lowest WAN is almost 1/3 of the 2 faster WANs, how is propose to set them?

Will try and get back.

You have 118 Mbps total. The 18M circuit is 15.2% of that. I would try a weight of 3 on each of the 50M circuits and a weight of 1 on the 18M circuit. That should put 1 state out of every 7 (14.2%) on the 18M circuit.

It is going to be pretty rare to get a speed test site to show you an aggregate of all the circuits on a load-balanced group. It just doesn't work that way. iperf3 with something like -P14 might get you closer.

Load Balancing works really well with lots of users and lots of states coupled with realistic expectations.

Thank you,

I will try the suggestions.

Out of curiosity, for all I know the APU has three interfaces. Does that mean your LAN connection is wireless?

Please read the topic ;), I am using one interface with VLANs in order to have 2 WANs from one physical.
