Difference between two Add load balancer pages in UI

[Syed Ahmed]

Hi All,

In the UI there are two places where we can add a loadbalancer rule.
1) Network-> myNetwork -> Add Load Balancer tab
2) Network -> myNetwork -> View IP Addresses -> [IP] -> Configuration -> 
LoadBalancing ( View All )


What is the difference between those two? Adding a rule on (2) seems to 
work but when I try to add it on (1) it fails saying cannot allocate 
source IP.

Thanks,
