Load Balance and Port Redirection

[dpa]

Hi!

I have two WANs, 20Mbps and 10Mbps download speeds respectively. I configured them with the same priority, Tier 1.

If I will set a rule to redirect ports HTTP, HTTPS, DNS, FTP to use 1st WAN as the gateway, and the rest of ports to 2nd WAN, what will happen to Load Balancing? If 1st WAN will be exhausted, will it balance further HTTP requests to 2nd WAN?

Or will it cancel the load balancing as the ports are already assigned to which wans?
