Hi All,

I'm using virtualbox 4.3.15 on Windows 2008 Server. I want to port-forward UDP traffic on port 1691 to my Linux VM at 10.0.88.11:1691.

I enter:

vboxmanage natnetwork modify -t NCeMonNet -p "se1691:udp:[][10.0.88.11]:1691

but the display shows tcp instead of udp and the port shows LISTENING for TCP.

Can anyone help me to understand how to establish port forwarding for UDP?


D:\Program Files\Oracle\VirtualBox>vboxmanage list natnets
NetworkName: NCeMonNet
IP: 10.0.88.1
Network: 10.0.88.0/24

That's actually a bug which will be fixed in the next maintenance release. The string was wrongly parsed.

Thanks, Frank. Any idea when that comes out?
