Hello there,
I'm facing a network issue here:

Host: Windows XP SP3
Guest: Debian Etch
VB: 2.1.0

Using network as "Host Interface" and static IP on Linux.

Actually it works. But only for the 1st time I start VM. If I stop VM and then start it again, I can't get network to work. Always got "Network Unreachable"

I always have to reboot Host machine to get it working again.

Somebody facing same issue? Or better, somebody know how fix it ?

The error you get, is that on the Host or the Guest? If it's on the Host, have you tried a repair on the interface you use? Is it by chance a wireless interface? If it's wifi, it might be disconnected without showing that. A repair often fixes these things.

Thanks for your reply.

Nope, I got this from Guest OS.

I played some more time with this issue.

Looks like Guest OS is tyring to get IP using NAT mode network even using HIF interface. I figure out that turning DHCP to get IP automatically in Guest OS, It receives DHCP RELEASE from 10.0.2.2 instead my Local Network.

That's why my network doesn't work when I give static IP to Guest? Looks like I'm attached to 'NAT mode' network in someway...

Just wondering, I really don't know what is happening here.

Some things I think is valid to comment:
Host OS has 2 VPN network interfaces (Tap Win 32 V8 Adapter and AGN Virtual Network Adapter)

Thanks!

If you attach the interface to NAT (which is the default when you create a VM), you can't set a static address in your own network range. DHCP is the only way to get it working.
If you want to have the VM take a part of your own network, you need HIF. See the manual for more info on VB Networking.

I did that already. I'm not using NAT. Its set to work as HIF.

Well, something funny is happening:

I do a ping -t from Host OS and put Guest to reboot.

When Guest OS bring up eth0 I got a single ping reply. After that, no response or networking from Guest OS for about some 3 minutes.
Then, networking starts to work again...

That's weird! Why network doesn't work just after is it started in Guest OS??
Any clues ?

EDIT1: Looks like networking stop to work after some time.
If I start to ping from guest to host, it back to work again, without no actions...

EDIT2: even Networking between Host and Guest start to work, I can't reach my network Gateway from Guest.

Host IP: 192.168.1.10
Guest IP: 192.168.1.11
GW: 192.168.1.1

Do you have a firewall on the Host running? It might cause problems with the network of the Guest.

no firewalls nor antivirus. also I disabled MAC Address filter on my WRT54G wifi router.
