Can a PIX block internet radio?

Can a PIX stop PC's from being able to receive Internet radio? PC's on inside interface, Internet on outside interface. Thanks, Bill.

Re: Can a PIX block internet radio?

It can with an outbound access-list, but you'll have to do some investigation as to what IP address the PC is connecting to to be able to stop it. If you can determine what port they're all connecting on then that would be easier to stop.

The easiest way to see what the PIX is allowing is to start Internet Radio from your PC, and then check the syslog on the PIX to see what connection it opened, this'll tell you the port number and the destination IP address.

I may be wrong but I think Radio uses TCP/UDP port 469, so something like the following would block all that:

access-list outbound deny tcp any any eq 469

access-list outbound deny udp any any eq 469

access-list outbound permit ip any any

access-group outbound in interface inside
