7298	bridged networking is not working	Peter		"I've configured bridged networking for windows XP SP3 guest on eth0 interface of my PC. Now, I've set 192.168.56.103/24 - for windows and 192.168.56.35/24 for linux (manually, no dhcp because dhcp is not working too, I see requests but no answers from host) but still I'm unable to ping neither from windows linux, neither from linux windows. Attaching tcpdump shows different pictures in this both cases:

If I ping from windows linux host I do see arp requests like:

{{{
10:11:11.332662 ARP, Request who-has 192.168.56.35 tell 192.168.56.103, length 46
}}}

If I ping from linux windows I see NO packets - they are missed in limbo.

As for networking setup on host, here it is:
