Hi,
is the routing on the host/guest machines correct?
Example:
LAN --------------+------------- 192.168.1.*
| real eth adapter 192.168.1.1
+-+-+
host OS | |
+-+-+ 192.168.2.1
| virt. eth adapter
+-+-+ 192.168.2.2
guest OS | |
+---+
On the Guest you need to set the default route to eth0:
$ route add default eth0
On the LAN you have to tell the machines to route packets for
192.168.2.* through the host (Assuming they are Windows):
C:\> route -p add 192.168.2.0 mask 255.255.255.0 192.168.1.1
If you use the same subnet for host/guest and lan, the host has to do
bridging of IP-Packets between the two interfaces, i have no idea how
to do this on NT.....
HTH,
