Nother selinux denial to be dealt with.

Greetings;

Verizon makes life a bitch by violating common carrier rules when the block 
port 80 to keep their customers from running a web server.  But port 85 
appears to be an unassigned port, and I have successfully used it to test when 
selinux, privoxy and squid were not running.  Now they are, and an attempted 
connect to http://gene.homelinux.net:85 now gets a 503 cuz selinux denies it.

As saved from setroubleshooter:
=================
Summary:

SELinux is preventing the privoxy(/usr/sbin/privoxy) (privoxy_t) from connecting
to port 85.

Detailed Description:

SELinux has denied the privoxy(/usr/sbin/privoxy) from connecting to a network
port 85 which does not have an SELinux type associated with it. If
privoxy(/usr/sbin/privoxy) is supposed to be allowed to connect on this port,
you can use the semanage command to add this port to a port type that privoxy_t
can connect to. semanage port -L will list all port types. Please file a bug
report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against the
selinux-policy package. If privoxy(/usr/sbin/privoxy) is not supposed to bind to
this port, this could signal a intrusion attempt.

Allowing Access:

If you want to allow privoxy(/usr/sbin/privoxy) to connect to this port semanage
port -a -t PORT_TYPE -p PROTOCOL 85 Where PORT_TYPE is a type that privoxy_t can
connect.

==================
What can I do to allow this?  The above isn't precise enough for me to go stumbling around.

2nd, do these mailing lists echo each other?  If so, sorry about hitting both.
