For some reason my last reply didn't follow the thread down...
Just incase it was missed.

Do you have the correct NAT and forwarding options set ?

I use :-
-A POSTROUTING -s 192.168.1.0/255.255.255.0 -o eth0 -j SNAT --to-source <public IP>

If nothing else on your network has that IP (demonstrated by your ping) then it's a nat/routing issue that is preventing your ve's from accessing the internet.

Also, I went to the trouble of looking the MAC address up

MAC Address
Prefix Vendor
0017E0 Cisco Systems

It looks like your cisco router is doing as I suggested and proxy arping.

Also from your arp tests, it shows the arp responses are comming from your public side (The cisco Router).
