[squid-users] udp ports

Hi

do these ports need to be available.

Im using my machine as a transparent proxy and I doubt that any of my
clients are making connections on those ports.

gate:~# netstat -nalpu
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address
State PID/Program name
udp 0 0 0.0.0.0:3130 0.0.0.0:*
         24857/(squid)
udp 0 0 0.0.0.0:32885 0.0.0.0:*
         24857/(squid)

If these ports dont have to be available, anyone know how I can remove them.

Kind Regards and thanks in advance.
