My WAN1 link is unmetered while my WAN2 is a metered connection but at a much faster connection speed. As such I want to give priority to web browsing to WAN2 and generally use WAN1 link for downloads such as ITunes podcast downloads, system update downloads, etc. as these are generally done at non-peak hours. I know that under System Maintenance I can bind certain IP address or ports to a specific WAN link. Does anyone know what port is used for ITunes downloads or for that matter any download? Do downloads use a different port than the standard port 80 or 8080 for web browsing? If so I'd like to bind this port to WAN1 so any downloads will use the unmetered connection. Any and all suggestions appreciated, thanks.
