How can my client work through a firewall/proxy server?

  If you are running through separate proxies for each service, you
  shouldn't need to do anything.  If you are working through sockd, you
  will need to "socksify" your application.  Details for doing this can
  be found in the package itself, which is available at:

       ftp://ftp.net.com/socks.cstc/socks.cstc.4.2.tar.gz

  you can get the socks faq at:
