Please see this thread: http://forums.virtualbox.org/viewtopic.php?f=1&t=38093&start=0 I can't get 4.0 to use same port for both TCP and UDP port forwarding? In 3.x versions this has been working well using VBoxManage (early versions used ""setextradata"", later versions using ""modifyvm"" as shown here): {{{ VBoxManage.exe modifyvm ""my_vm"" --natpf1 ""tcp_pf"",tcp,,32512,,32512 VBoxManage.exe modifyvm ""my_vm"" --natpf1 ""udp_pf"",udp,,32512,,32512 }}} Now with 4.0 I can only set both rules if ports are not the same. Sasquatch confirmed in the GUI that the second rule is discarded. VBoxManage gives error message on the second rule, stating it already exists. Kind regards, --appyface " defect closed other VirtualBox 4.0.0 fixed Windows Windows
