I am trying to run multiple network nodes (A, B, C, D and E). Each
node requires unique IP address to be assigned. Due to crunch of linux
machines at home, I planned to use Virtual IP, running A, B, C and D
on Machine 1 and E on Machine 2. An IP packet is expected to travel
from D to C, C to B and B to outside network. On the other way around
from the outside network -> B, B->C and C->D. Lets I ping a machine
in the outside network. I can see the packet traversing D->C, C->B B-
>outside network and on the way around outside network ->B, B->C, C-
>D, but the ping response is not shown at command prompt. This means
the packet is getting dropped at the IP stack of Machine 2.
When I had close look at the packets, I could observe that packets
which are coming out from C->D were with Ethernet MAC address being
all zeroes. This might be the cause of IP packets getting dropped. Is
there a solution I can avoid so that packets are not dropped. When I
start doing pinging C from D, ping packets from the outside network
gets displayed. For time being temporary solution, I start redundant
ping which keeps pinging C from D.
This problem is almost killing my multiple node issue. I kindly
request for help.

The fact of your multi-posting such an ill-advised task to so many Linux
newsgroups indicates that you have a penchant for needlessly working against
yourself, wasting not only your own effort but everyone else's as well.

Good luck, as you're going to need it but almost certainly won't find it.
