Connect to QNX on VirtualBox with Momentics

I install QNX Neutrino OS on VirtualBox and Momentics on Win.

My Win10 PC IP is 192.168.1.4 and QNX IP is 10.0.2.15

In VB i forward port:

• TCP
• Host-adress 192.168.1.4
• Host-port 8000
• Guest-adress 10.0.2.15
• Guest-port 8000

I type "qconn" and did next -- first and second. But command "ping 10.0.2.15" from cmd return "Request timed out."

And QNX Target in Momentics return "Not connected" to each my attempts.

Thank you in advance for your help.

P.S.-- Sorry for my English.

I change VirtualBox to VMWare with same .iso and it just work.
