connection ports

[M.V.]

After starting the daemon I noticed that the application starts listen
on two random ports.
Having checked checking http://wiki.apache.org/cassandra/FAQ#ports I
gather that in my vanilla setup (listening on interface
192.168.100.30)
port => service/application
7000 => Cassandra cluster communication
7199 => JMX
8081 => MX4J/Http Adaptor - JMX Management Console
9160 => The Thrift client API
33653 => ???
58496 => ???

Because of very strict iptables setup, some clients such as cassandra-
gui.jar can't connect to this node because it (the client) attemps to
connect to one of this random ports as well as 9160 & 7199 ports
Any ideas?

Not a cassandra-gui issue.

I haven't manage to solve my problem - I'm behind a very strict
firewall so connections to random ports aren't possible.
But for the java experienced folks here is the solution
