Title: load balancing multi-wan
Post by: jasonblewis on February 26, 2018, 01:19:53 am: Hi,

I've tried setting up load balancing with my 2 ADSL connections as per the multi wan setup instructions. I set both WANs to the same tier but I don't see much in the way of "load balancing" it seems to always favour one of the WANs.

How does one test this to make sure its working as it is supposed to?

In https://forum.opnsense.org/index.php?topic=3969.msg14151#msg14151 (https://forum.opnsense.org/index.php?topic=3969.msg14151#msg14151) Franco states that its just round robin per connection, bit I don't think mine is even acheiving that. For example, If i do:
curl ipinfo.io/ip repeatedly, I'd expect it to get different WAN IPs from time to time as it would be sending out the request from one of the two WANs, but it seems to always get the same IP.

Any tips would be appreciated

tia

Have you tried put real workload on your opn sense and check Report => Health => Trafic ??

Cheers,
