Trying Delphi XE2, testing Mac OSX

 I'm trying the Mac stuff with no success, I've followed all instructions:

• Windows 7 IP is 192.168.2.2
• Install VirtualBox
• Install Mac OSX via VirtualBox 
• Install in Mac the paserver thing from Embarcadero
• Launch pasever at port 64211
• VirtualBox guest IP is 192.168.2.69 forwared to 192.168.2.2 port 50000

Ping to remote OS works, but telnet on port 50000 doesn't (neither on port 64211), therefore in Delphi it does not work..., it shows: [PAClient Error] Error: EIdSocketError: Socket Error # 10061

The configuration in VirtualBox:

And the configuration in Delphi:

With Windows Firewall disabled it also does not work, so I'm really lost, somebody has been success with this kind of configuration?
