Tutorials and FAQs / Load balancing/Failover based on bandwidth saturation
« on: February 03, 2018, 04:40:19 am »
First and foremost, I would like to thank you for your excellent job you doing with OPNsense, keep it up!
Now to my matter. I have two WANs, the first one is a 17Mbit/1Mbit line and the other one a 12mbit/1Mbit. What I'm trying to achieve and I can't get it to work properly is that I want to fallback to the second wan only if the first one is fully saturated.
Somehow I can make it to work by taking advantage of the bufferbloat, thank to the first one being an ADSL connection, and setting a trigger on high latency with WAN1 in tier 1 and WAN2 in tier 2. I have also tried load balancing with both WANs in the same tier with mixed results due to the second WAN being slower and worse quality-wise than the first one, low tier ISP with bad routing.
So I'm asking if there is a "proper" way to achieve that setup based solely on bandwidth saturation.
Thank you in advance.
