I am running VirtualBox (with XP-Guests and soon W7) on a Win2003-server. Just recently (and with help of a superuser), I was able to see the VM in the network (before I could only connect to the web and see the intranet from the VM, but not see the VM).
- IP of gateway: 192.168.1.1
- IP of host: 192.168.1.199
On the hosts's LAN-connections, I have a "VirtualBox Host-only network" and in its TCP/IP-settings have assigned the IP 192.168.1.51.
The VM still runs with automatic assignment of an IP and currently uses 192.168.1.5.
I hope this gives all info you may need, please just ask if I left out something...
edit: I see few people viewing the q and not responding. If I'm moving in the wrong direction or am doing something stupid (obvious for anyone but me) - please. add a comment ;)
