In order to use our tracker you must configure your client to use any port range that does not contain those ports
(a range within the region 49152 through 65535 is preferable, cf. IANA). Notice that some clients, like Azureus 2.0.7.0 or higher, use a single port for all torrents, while most others use one port per open torrent. The size of the range you choose should take this into account (best-practice ranges are typically less than 10 ports wide). There is no benefit whatsoever in choosing a wide range, and there are possible security implications.
