He already said he turned off the ICP port, so I'm guessing that isn't
it.  Also, the ICP port is 3130 by default, not 1414.

Squid also can use a udp port for snmp (default 3401).

FWIW, I found a couple of references to squid's use of a random high
udp port on the squid-user list.  The only responses I could find
indicated that this port is used for DNS.
