Juniper Simulator using Settings VirtualBox

Recently learn Juniper's firewall and find the simulator on the Internet. Based on http://bbs.hh010.com/thread-377313-1-1.html settings, but VirtualBox has been error-activated

Namedpipe#0 failed to connect to named pipe \\.\pipe\com_1 (verr_file_not_found). Return code: E_FAIL (0x80004005) components: Consolewrap interface: iconsole {872da645-4a9b-1727-bee2-5585105b9eed}

　

Finally change the settings a little bit to start normally

Port number: User Defined

Port mode: Host Pipeline

Uncheck "Connect to an existing channel or socket"
