virtualbox.org

here is the config on VirtualBox 3.0:

Host:
OS:Win Vista x64

Guest:
OS:Win XP x64
Network: Intel Pro/1000 MT Server, NAT

Now I am trying to forward port 3000 on host to 3389 on guest(the remote desktop port).

Here is what I did:
VBoxManage setextradata "WinXP" "VBoxInternal/Devices/e1000/0/LUN#0/Config/guestRDP/Protocol" TCP

VBoxManage setextradata "WinXP" "VBoxInternal/Devices/e1000/0/LUN#0/Config/guestRDP/GuestPort" 3389

VBoxManage setextradata "WinXP" "VBoxInternal/Devices/e1000/0/LUN#0/Config/guestRDP/HostPort" 3000

But it doesn't work.

Am I missing something or doing something wrong?

Thanks

So exactly what doesn't work? How did you test this? How do you make the connection? You're missing the most vital part of information in your post.

This is how I tested it:
1. on the Vista host, I used the remote desktop client to connect to localhost:9999. No connection established.

2. Then I used telnet localhost 9999 to test it, apprently no connection.

3. In the guest XP, I telnet localhost 3389, connection established, which means Remote desktop service in Guest XP was running.

4. I tried switch from NAT to Host-only network mode, I am able to connect to Guest XP's remote desktop. But no luck with NAT.

And both firewalls are turned off.

Why the hell are you connecting to a closed port? You forwarded port 3000, not 9999.

sorry, that was a typo cause I tried to change to another port. It was 9999, I double checked the xml file.

Any firewall running on the Host? Run a port scan on the Host while the VM is running to see what open ports you have.
