I'm going to use Winamp for listening internet radio. Sunbelt Kerio PFW is used and its usage is based on Packet Filter Module.
How should I connect to broadcast servers to have to have opened only limited number of ports instead of a wide range of ports ? What stream format is best for use from security point of view ? What form of URL's do then apply ? I wish to have define in my FW a packet filter rule opening a small number of ports. Now I have open inbound for TCP and remote port range 1000 to 65535, local port range 1024 to 4999. But I think there could be a way for listening internet radio, where I don't have to open so many of ports.
Thanks for any hints in advance.
