General Discussion / Re: WAN Balancing Not working
« on: February 20, 2024, 05:53:04 am »
I wanted to add my two cents into this troubleshooting effort - I was having similar issues in getting load balancing to work - nothing seemed to do the trick but like everyone here, failover seemed fine.
However, I did get load balancing working - there was one checkbox that is absent from the instructions that I think was the key - when you create the new DNS firewall rule I also checked "Quick" (apply the setting immediately on match). After that, DNS resolution worked just fine with load balancing setup as per opnsense's documentation.
My theory is that if you don't select that box, the rest of the firewall rules get applied and something overwrite the DNS outbound rule or messes up routing somehow.
Hope this helps - please post a reply if this also fixed your load balancing issue.
