When you follow the Enable/Disable Client Debugging link, a list of peer addresses that are currently enabled for debugging is displayed. The list of peer addresses enabled by default at server startup is specified in the ClientDebug configuration parameter. The ClientDebug parameter is set on an individual virtual server basis.
You can choose to disable any of those addresses, or enable your own address, or enable any other address.
Note that any peer addresses you specify in this manner will be enabled for client debugging only until the server is shut down or manually disabled. Only the peer addresses enabled with the ClientDebug parameter will be enabled for client debugging permanently.
