Load balancer set-up

Hi,
Just trying to set-up the load balancer. My service is running at port 81 on each host. Would like to set-up Load balancer which can spread the requests to service running on each host. While configuring the load balancer, I set source port as 80 and target port as 81. And selected the target service from the drop down too. While trying to access the service at port 80 now, it is giving 503 error… I am missing something here? Appreciate help.

thx

Could you provide screenshots of your LB setup in Rancher?

Thanks Chas, I got that sorted out… Thanks for your help…
