enableIceGatheringOnAnyAddressPorts

When enabled ports not bound to 'any' specific network interface will be used, in addition to normal ports bound to the enumerated interfaces. Without this flag, these "any address" ports would only be used when network enumeration fails or is disabled. But under certain conditions, these ports may succeed where others fail, so they may allow the application to work in a wider variety of environments, at the expense of having to allocate additional candidates.
