[Users] Can't ping VE from Host

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
          inet addr:72.232.35.21  Bcast:72.255.255.255  Mask:255.255.255.248

One of my VEs looks like:

          UP BROADCAST POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1

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
