Load Balancing & Priorities

[BenKenobi]

I have two WAN connections, I have tried numerous times to get load balancing working 'reliably' but although I can get it to function performance is far from satisfactory, DNS becomes unreliable and unacceptably slow.

I can configure load balancing but I run my own DNS server, I don't see why I should need to configure ANY DNS rule in the firewall to get load balancing to function, but if you don't then no outgoing connections are possible at all. I neither need nor desire any of the DNS facilities offered by OPNSense or FreeBSD, I can't even fathom why load balancing would require a DNS rule unless the implementation of load balancing is flawed.

I decided therefore that I'd do some manual balancing by changing gateway priorities - i.e. 255, 254, 253 ... where the lowest number is supposed to be the highest priority and therefore used, even after a reboot and clearing states the system flat refuses to use the lowest number unless I disable the other connection (with a priority of 255) entirely and seems to take the default to be the lowest / first defined 'physical' WAN NIC.

Although I have a different priority set for each WAN and the 'Allow default gateway switching' is enabled the system ignores the priorities and sticks to the gateway with the highest number i.e. 255.

This is starting to get a tad frustrating - this load balancing hasn't worked reliably since V19.
