Note that VNET_PUBLICIPS="192.168.3.1-192.168.5.254" is, I think, incorrect. PUBLICIPS only accepts ranges within a single class C. You should write instead:
VNET_PUBLICIPS="192.168.3.1-192.168.3.255 192.168.4.0-192.168.4.255 192.168.5.0-192.168.5.254"
Note sure it has an effect though, since you now test with --addressing private.
We need some upstream advice on this...
