Guys,
I'm having a problem and not sure what to do with it.
I have multiple VEs set up on the 192.168.4.0 address space. I can ping
between VEs on this address space just find. I can also ping to the
internet from the VEs through SNAT'ing. However, I cannot ping a VE from
the host.
My host's network configuration looks like this:
eth0 Link encap:Ethernet HWaddr 00:0E:0C:68:64:37

Again, I can ping just fine from between VEs and from VE--->Internet,
but not from hardware host to VE. This obviously prevents me from doing
port forwarding to VEs.
Can someone help me out?
Thanks!
John

John,
Could you post also the routing table in the above VE?
Probably it'll help to understand, what's wrong.
