* By default, port 30005 is used for communications between RAS Shell and RAS Agents. A registry key may be added and an alternative port may be specified. In case the newly assigned port or 30005 are not available, a dynamic port between 31005 and 31015 range will be used. The registry key can be added as follows: HKLM\SOFTWARE\Parallels\AgentIPC Value: Port Type: REG_DWORD
