Multiple UDP Port Configuration
I have 5 virtual server configurations to perform a pass-through connection for a web based application. The web front-end connection (for login page, authentication) is made on HTTPS/443. Once a user uploads a file for example, the transmission is established over TCP port (e.g. 12345) and transmits over UDP (12345). In the event that the propriety port can't be used (i.e. an external party blocks that port) a backup port is available being TCP (e.g. 6789) and UDP (6789). The configuration works if 1 set of virtual servers are enabled and the other is disabled. If both virtual server ports are open it fails. How do I best configure the virtual server to utilise these UDP ports? Would it better to collapse the ports into effectively a single Virtual Server and use some type of round-robin configuration or maybe even a policy configuration to monitor the incoming transmission and direct to the appropriate virtual server?
