virtualbox

I'm running Ubuntu using VirtualBox to test a server application, but I couldn't get it work the communication.

I used nmap to check whether the port is open or not:

nmap  -T4 -n vbip -p 30000

Host is up (0.00061s latency).
PORT      STATE    SERVICE
30000/tcp filtered unknown

when I'm checking the port inside the VirtualBox, than the port is open

Host is up (0.00061s latency).
PORT      STATE    SERVICE
30000/tcp open unknown

I'm using bridge connection, does the VB filter the ports?
