Hi, Hakan. Sorry to be coming so late to the party...
I'm in the process of re-installing VPC on my T43 right now (need to reboot), but I wanted to throw a couple things out for general consumption...
1. Under Windows, the command to display your routing table is
route print <Enter>
2. To get to your local systems, a default route is not needed (if
using Virtual Switch), as you are staying on your local network.
3. Try to ping the IP address of your local machine, as assigned
under eCS. This should give us an idea as to whether traffic is
moving between the virtual machine and the physical one.
4. It is indeed possible to obtain an IP address form a DHCP request
and still not be able to get any traffic to pass. I see this *from
time to time* particularly when troubleshooting wireless networks.
5. Can you ping the VPC guest address from the VPC host?
6. I take it that you are attempting to ping addresses and not names.
Name resolution is a completely different matter (obviously).
7. Dump your ARP table from the VPC guest to see what you've got:
arp -a <Enter>
8. Check the arp tables in your other machines on the network and see
if they have entries for your virtual machine listed. Try pinging
your virtual machine IP from other machines (assuming a ping from
the host is successful) to populate the arp tables on those other
machines.
9. I hope you are using Virtual Switch on your wired interface and
not on your wireless one, as Virtual Switch *does not work
reliably* over 802.11 links. I had some discussion with Achim a
few years ago in this regard, but as VPC was (by necessity)
discontinued, the issue (an enhancement request, actually, as this
was not a bug, but a known condition) was never addressed.
10. Are you certain that you do not have another DHCP server anywhere
on your network which could be assigning duplicate addresses (see
point 4, above, as this is a common cause).
The above are related to DHCP specifically, and not to troubleshooting TCP/IP in general.
More suggestions later.
