To get to this panel, press button Settings in JonDo's main window, then choose the entry Portlistener from the list to the left.
For JonDo to anonymize communication over the internet, it must be connected between the browser and the server in the internet. This type of intermediate station is generally called a proxy. Most programs that communicate with the internet can connect through such a proxy. The necessary settings for such a connection are: the name of the computer (host) on which the proxy is running, and the port number under which the proxy accepts requests. In the case of JonDo, the host is the local computer itself and the port number is 4001 as default. This setting can almost always be left at the default.
