VirtualBox Networkworking

I have a VirtualBox Vista host w/ip 192.168.5.101 and a Ubuntu guest with DCHP ip 192.168.5.108. The guest is configured for Host Interface. The guest can ping all other machines in the network and get to the internet. The host can ping all the machines in the network AS WELL AS the guest OS at 108. Any Ideas?

So what's the problem? This is exactly as expected. If you want the guest to be hidden, you'll have to firewall it, unless you don't need _any_ other computers to be able to reach it, in which case you can use a NAT interface.

This is exactly my configuration (because I can't get Ubuntu to install on this laptop natively) and for the first time ever I have Host interfaces working smoothly over both wired and wireless host interfaces.

The problem is the guest cannot ping the host. They have ips on the same subnet. Is that a limitation of host interface.. You cannot ping the host from guest?

Host is Windows Vista with firewall open to all hosts in 192.168.5.0/24 for TCP and UDP. Ubuntu guest (8.10) gives this error to ssh attempt to host os @ .101

ssh: connect to host 192.168.5.101 port 22: No route to host

fosiul01

you should try to to ssh from windows vista to ubutu by using putty

You have it right.

Here is route table. The DG is the private side of my router.

Kernel IP routing table

fosiul01: Now is the time to apologize for wasting your time. I was able to open a smb file session from ubuntu to the host. that got me looking at fw configs. Its gotta be in there somewhere. Especially if I can browse the host filesystem from the guest.

What does "route -n" show?
