Hi,

I'm using Jenkins 1.425-SNAPSHOT deployed like this :

• OS : Ubuntu 11.04
• AppServer : Apache Tomcat 6.0.32
• Reverse Proxy : Apache HTTPd with mod-proxy-httpd
  Jenkins is exposed only using https on the apache side.
  The reverse proxy has this sort of config :

      ProxyRequests           Off
      ProxyPreserveHost       On
      ProxyPass               /       http://localhost:20020/ acquire=1000 retry=30
      ProxyPassReverse        /       http://localhost:20020/
      <Proxy *>
          Order deny,allow
          Allow from all
      </Proxy>
  

  I cannot use the Jenkins CLI if the firewall is activated and I receive a Connection Timeout Error.
  Jenkins probably opens a communication port (JNPL ?) that the CLI cannot use.
