Yes, we use slirp for our user-mode NAT. And there is code in VirtualBox that allows one to configure port forwarding. There is nothing in the normal frontends/GUIs which allows you to get at these settings, but you can specify the config options "UDP" (boolean, default true), "HostPort", "GuestPort" and "GuestIP". To set these options (I assume that the guest NIC using NAT is the first one), one uses VBoxManage setextradata VMNAME "/Devices/pcnet/0/LUN#0/Config/UDP" 0 and so on. The GuestIP is specified as a string. If it doesn't work (it's possible that the VM will refuse to start if you set these config options), make sure you remove everything you added by omitting the value for a particular key. AFAIK that code hasn't been in use, so please let me know if it works or not. -- Klaus Espenlaub InnoTek Systemberatung GmbH, http://www.innotek.de _______________________________________________ vbox-users mailing list [email protected] http://vbox.innotek.de/mailman/listinfo/vbox-users
